# Interface to Mathematica#

The Mathematica interface will only work if Mathematica is installed on your computer with a command line interface that runs when you give the math command. The interface lets you send certain Sage objects to Mathematica, run Mathematica functions, import certain Mathematica expressions to Sage, or any combination of the above. The Sage command:

sage: print(mathematica._install_hints())
...

>>> from sage.all import *
>>> print(mathematica._install_hints())
...


To send a Sage object sobj to Mathematica, call mathematica(sobj). This exports the Sage object to Mathematica and returns a new Sage object wrapping the Mathematica expression/variable, so that you can use the Mathematica variable from within Sage. You can then call Mathematica functions on the new object; for example:

sage: mobj = mathematica(x^2-1)             # optional - mathematica
sage: mobj.Factor()                         # optional - mathematica
(-1 + x)*(1 + x)

>>> from sage.all import *
>>> mobj = mathematica(x**Integer(2)-Integer(1))             # optional - mathematica
>>> mobj.Factor()                         # optional - mathematica
(-1 + x)*(1 + x)


In the above example the factorization is done using Mathematica’s Factor[] function.

To see Mathematica’s output you can simply print the Mathematica wrapper object. However if you want to import Mathematica’s output back to Sage, call the Mathematica wrapper object’s sage() method. This method returns a native Sage object:

sage: # optional - mathematica
sage: mobj = mathematica(x^2-1)
sage: mobj2 = mobj.Factor(); mobj2
(-1 + x)*(1 + x)
sage: mobj2.parent()
Mathematica
sage: sobj = mobj2.sage(); sobj
(x + 1)*(x - 1)
sage: sobj.parent()
Symbolic Ring

>>> from sage.all import *
>>> # optional - mathematica
>>> mobj = mathematica(x**Integer(2)-Integer(1))
>>> mobj2 = mobj.Factor(); mobj2
(-1 + x)*(1 + x)
>>> mobj2.parent()
Mathematica
>>> sobj = mobj2.sage(); sobj
(x + 1)*(x - 1)
>>> sobj.parent()
Symbolic Ring


If you want to run a Mathematica function and don’t already have the input in the form of a Sage object, then it might be simpler to input a string to mathematica(expr). This string will be evaluated as if you had typed it into Mathematica:

sage: mathematica('Factor[x^2-1]')          # optional - mathematica
(-1 + x)*(1 + x)
sage: mathematica('Range[3]')               # optional - mathematica
{1, 2, 3}

>>> from sage.all import *
>>> mathematica('Factor[x^2-1]')          # optional - mathematica
(-1 + x)*(1 + x)
>>> mathematica('Range[3]')               # optional - mathematica
{1, 2, 3}


If you don’t want Sage to go to the trouble of creating a wrapper for the Mathematica expression, then you can call mathematica.eval(expr), which returns the result as a Mathematica AsciiArtString formatted string. If you want the result to be a string formatted like Mathematica’s InputForm, call repr(mobj) on the wrapper object mobj. If you want a string formatted in Sage style, call mobj._sage_repr():

sage: mathematica.eval('x^2 - 1')           # optional - mathematica
2
-1 + x
sage: repr(mathematica('Range[3]'))         # optional - mathematica
'{1, 2, 3}'
sage: mathematica('Range[3]')._sage_repr()  # optional - mathematica
'[1, 2, 3]'

>>> from sage.all import *
>>> mathematica.eval('x^2 - 1')           # optional - mathematica
2
-1 + x
>>> repr(mathematica('Range[3]'))         # optional - mathematica
'{1, 2, 3}'
>>> mathematica('Range[3]')._sage_repr()  # optional - mathematica
'[1, 2, 3]'


Finally, if you just want to use a Mathematica command line from within Sage, the function mathematica_console() dumps you into an interactive command-line Mathematica session. This is an enhanced version of the usual Mathematica command-line, in that it provides readline editing and history (the usual one doesn’t!)

## Tutorial#

We follow some of the tutorial from http://library.wolfram.com/conferences/devconf99/withoff/Basic1.html/.

For any of this to work you must buy and install the Mathematica program, and it must be available as the command math in your PATH.

### Syntax#

Now make 1 and add it to itself. The result is a Mathematica object.

sage: m = mathematica
sage: a = m(1) + m(1); a                # optional - mathematica
2
sage: a.parent()                        # optional - mathematica
Mathematica
sage: m('1+1')                          # optional - mathematica
2
sage: m(3)**m(50)                       # optional - mathematica
717897987691852588770249

>>> from sage.all import *
>>> m = mathematica
>>> a = m(Integer(1)) + m(Integer(1)); a                # optional - mathematica
2
>>> a.parent()                        # optional - mathematica
Mathematica
>>> m('1+1')                          # optional - mathematica
2
>>> m(Integer(3))**m(Integer(50))                       # optional - mathematica
717897987691852588770249


The following is equivalent to Plus[2, 3] in Mathematica:

sage: m = mathematica
sage: m(2).Plus(m(3))                   # optional - mathematica
5

>>> from sage.all import *
>>> m = mathematica
>>> m(Integer(2)).Plus(m(Integer(3)))                   # optional - mathematica
5


We can also compute $$7(2+3)$$.

sage: m(7).Times(m(2).Plus(m(3)))       # optional - mathematica
35
sage: m('7(2+3)')                       # optional - mathematica
35

>>> from sage.all import *
>>> m(Integer(7)).Times(m(Integer(2)).Plus(m(Integer(3))))       # optional - mathematica
35
>>> m('7(2+3)')                       # optional - mathematica
35


### Some typical input#

We solve an equation and a system of two equations:

sage: # optional - mathematica
sage: eqn = mathematica('3x + 5 == 14')
sage: eqn
5 + 3*x == 14
sage: eqn.Solve('x')
{{x -> 3}}
sage: sys = mathematica('{x^2 - 3y == 3, 2x - y == 1}')
sage: print(sys)
2
{x  - 3 y == 3, 2 x - y == 1}
sage: sys.Solve('{x, y}')
{{x -> 0, y -> -1}, {x -> 6, y -> 11}}

>>> from sage.all import *
>>> # optional - mathematica
>>> eqn = mathematica('3x + 5 == 14')
>>> eqn
5 + 3*x == 14
>>> eqn.Solve('x')
{{x -> 3}}
>>> sys = mathematica('{x^2 - 3y == 3, 2x - y == 1}')
>>> print(sys)
2
{x  - 3 y == 3, 2 x - y == 1}
>>> sys.Solve('{x, y}')
{{x -> 0, y -> -1}, {x -> 6, y -> 11}}


### Assignments and definitions#

If you assign the mathematica $$5$$ to a variable $$c$$ in Sage, this does not affect the $$c$$ in Mathematica.

sage: c = m(5)                          # optional - mathematica
sage: print(m('b + c x'))               # optional - mathematica
b + c x
sage: print(m('b') + c*m('x'))          # optional - mathematica
b + 5 x

>>> from sage.all import *
>>> c = m(Integer(5))                          # optional - mathematica
>>> print(m('b + c x'))               # optional - mathematica
b + c x
>>> print(m('b') + c*m('x'))          # optional - mathematica
b + 5 x


The Sage interfaces changes Sage lists into Mathematica lists:

sage: m = mathematica
sage: eq1 = m('x^2 - 3y == 3')          # optional - mathematica
sage: eq2 = m('2x - y == 1')            # optional - mathematica
sage: v = m([eq1, eq2]); v              # optional - mathematica
{x^2 - 3*y == 3, 2*x - y == 1}
sage: v.Solve(['x', 'y'])               # optional - mathematica
{{x -> 0, y -> -1}, {x -> 6, y -> 11}}

>>> from sage.all import *
>>> m = mathematica
>>> eq1 = m('x^2 - 3y == 3')          # optional - mathematica
>>> eq2 = m('2x - y == 1')            # optional - mathematica
>>> v = m([eq1, eq2]); v              # optional - mathematica
{x^2 - 3*y == 3, 2*x - y == 1}
>>> v.Solve(['x', 'y'])               # optional - mathematica
{{x -> 0, y -> -1}, {x -> 6, y -> 11}}


### Function definitions#

Define mathematica functions by simply sending the definition to the interpreter.

sage: m = mathematica
sage: _ = mathematica('f[p_] = p^2');   # optional - mathematica
sage: m('f[9]')                         # optional - mathematica
81

>>> from sage.all import *
>>> m = mathematica
>>> _ = mathematica('f[p_] = p^2');   # optional - mathematica
>>> m('f[9]')                         # optional - mathematica
81


### Numerical Calculations#

We find the $$x$$ such that $$e^x - 3x = 0$$.

sage: eqn = mathematica('Exp[x] - 3x == 0') # optional - mathematica
sage: eqn.FindRoot(['x', 2])                # optional - mathematica
{x -> 1.512134551657842}

>>> from sage.all import *
>>> eqn = mathematica('Exp[x] - 3x == 0') # optional - mathematica
>>> eqn.FindRoot(['x', Integer(2)])                # optional - mathematica
{x -> 1.512134551657842}


Note that this agrees with what the PARI interpreter gp produces:

sage: gp('solve(x=1,2,exp(x)-3*x)')
1.512134551657842473896739678              # 32-bit
1.5121345516578424738967396780720387046    # 64-bit

>>> from sage.all import *
>>> gp('solve(x=1,2,exp(x)-3*x)')
1.512134551657842473896739678              # 32-bit
1.5121345516578424738967396780720387046    # 64-bit


Next we find the minimum of a polynomial using the two different ways of accessing Mathematica:

sage: mathematica('FindMinimum[x^3 - 6x^2 + 11x - 5, {x,3}]')  # optional - mathematica
{0.6150998205402516, {x -> 2.5773502699629733}}
sage: f = mathematica('x^3 - 6x^2 + 11x - 5')  # optional - mathematica
sage: f.FindMinimum(['x', 3])                  # optional - mathematica
{0.6150998205402516, {x -> 2.5773502699629733}}

>>> from sage.all import *
>>> mathematica('FindMinimum[x^3 - 6x^2 + 11x - 5, {x,3}]')  # optional - mathematica
{0.6150998205402516, {x -> 2.5773502699629733}}
>>> f = mathematica('x^3 - 6x^2 + 11x - 5')  # optional - mathematica
>>> f.FindMinimum(['x', Integer(3)])                  # optional - mathematica
{0.6150998205402516, {x -> 2.5773502699629733}}


### Polynomial and Integer Factorization#

We factor a polynomial of degree 200 over the integers.

sage: R.<x> = PolynomialRing(ZZ)
sage: f = (x**100+17*x+5)*(x**100-5*x+20)
sage: f
x^200 + 12*x^101 + 25*x^100 - 85*x^2 + 315*x + 100
sage: g = mathematica(str(f))            # optional - mathematica
sage: print(g)                           # optional - mathematica
2       100       101    200
100 + 315 x - 85 x  + 25 x    + 12 x    + x
sage: g                                  # optional - mathematica
100 + 315*x - 85*x^2 + 25*x^100 + 12*x^101 + x^200
sage: print(g.Factor())                  # optional - mathematica
100               100
(20 - 5 x + x   ) (5 + 17 x + x   )

>>> from sage.all import *
>>> R = PolynomialRing(ZZ, names=('x',)); (x,) = R._first_ngens(1)
>>> f = (x**Integer(100)+Integer(17)*x+Integer(5))*(x**Integer(100)-Integer(5)*x+Integer(20))
>>> f
x^200 + 12*x^101 + 25*x^100 - 85*x^2 + 315*x + 100
>>> g = mathematica(str(f))            # optional - mathematica
>>> print(g)                           # optional - mathematica
2       100       101    200
100 + 315 x - 85 x  + 25 x    + 12 x    + x
>>> g                                  # optional - mathematica
100 + 315*x - 85*x^2 + 25*x^100 + 12*x^101 + x^200
>>> print(g.Factor())                  # optional - mathematica
100               100
(20 - 5 x + x   ) (5 + 17 x + x   )


We can also factor a multivariate polynomial:

sage: f = mathematica('x^6 + (-y - 2)*x^5 + (y^3 + 2*y)*x^4 - y^4*x^3')  # optional - mathematica
sage: print(f.Factor())                  # optional - mathematica
3                  2    3
x  (x - y) (-2 x + x  + y )

>>> from sage.all import *
>>> f = mathematica('x^6 + (-y - 2)*x^5 + (y^3 + 2*y)*x^4 - y^4*x^3')  # optional - mathematica
>>> print(f.Factor())                  # optional - mathematica
3                  2    3
x  (x - y) (-2 x + x  + y )


We factor an integer:

sage: # optional - mathematica
sage: n = mathematica(2434500)
sage: n.FactorInteger()
{{2, 2}, {3, 2}, {5, 3}, {541, 1}}
sage: n = mathematica(2434500)
sage: F = n.FactorInteger(); F
{{2, 2}, {3, 2}, {5, 3}, {541, 1}}
sage: F[1]
{2, 2}
sage: F[4]
{541, 1}

>>> from sage.all import *
>>> # optional - mathematica
>>> n = mathematica(Integer(2434500))
>>> n.FactorInteger()
{{2, 2}, {3, 2}, {5, 3}, {541, 1}}
>>> n = mathematica(Integer(2434500))
>>> F = n.FactorInteger(); F
{{2, 2}, {3, 2}, {5, 3}, {541, 1}}
>>> F[Integer(1)]
{2, 2}
>>> F[Integer(4)]
{541, 1}


Mathematica’s ECM package is no longer available.

## Long Input#

The Mathematica interface reads in even very long input (using files) in a robust manner.

sage: t = '"%s"'%10^10000   # ten thousand character string.
sage: a = mathematica(t)        # optional - mathematica
sage: a = mathematica.eval(t)   # optional - mathematica

>>> from sage.all import *
>>> t = '"%s"'%Integer(10)**Integer(10000)   # ten thousand character string.
>>> a = mathematica(t)        # optional - mathematica
>>> a = mathematica.eval(t)   # optional - mathematica


Mathematica has an excellent InputForm function, which makes saving and loading Mathematica objects possible. The first examples test saving and loading to strings.

sage: # optional - mathematica
sage: x = mathematica(pi/2)
sage: print(x)
Pi
--
2
True
sage: n = x.N(50)
sage: print(n)
1.5707963267948966192313216916397514420985846996876
True

>>> from sage.all import *
>>> # optional - mathematica
>>> x = mathematica(pi/Integer(2))
>>> print(x)
Pi
--
2
True
>>> n = x.N(Integer(50))
>>> print(n)
1.5707963267948966192313216916397514420985846996876
True


## Complicated translations#

The mobj.sage() method tries to convert a Mathematica object to a Sage object. In many cases, it will just work. In particular, it should be able to convert expressions entirely consisting of:

• numbers, i.e. integers, floats, complex numbers;

• functions and named constants also present in Sage, where:

• Sage knows how to translate the function or constant’s name from Mathematica’s, or

• the Sage name for the function or constant is trivially related to Mathematica’s;

• symbolic variables whose names don’t pathologically overlap with objects already defined in Sage.

This method will not work when Mathematica’s output includes:

• strings;

• functions unknown to Sage;

• Mathematica functions with different parameters/parameter order to the Sage equivalent.

If you want to convert more complicated Mathematica expressions, you can instead call mobj._sage_() and supply a translation dictionary:

sage: m = mathematica('NewFn[x]')       # optional - mathematica
sage: m._sage_(locals={('NewFn', 1): sin})   # optional - mathematica
sin(x)

>>> from sage.all import *
>>> m = mathematica('NewFn[x]')       # optional - mathematica
>>> m._sage_(locals={('NewFn', Integer(1)): sin})   # optional - mathematica
sin(x)


For more details, see the documentation for ._sage_().

sage: P = mathematica('Plot[Sin[x],{x,-2Pi,4Pi}]')   # optional - mathematica
sage: filename = tmp_filename()                      # optional - mathematica
sage: P.save_image(filename, ImageSize=800)                # optional - mathematica

>>> from sage.all import *
>>> P = mathematica('Plot[Sin[x],{x,-2Pi,4Pi}]')   # optional - mathematica
>>> filename = tmp_filename()                      # optional - mathematica
>>> P.save_image(filename, ImageSize=Integer(800))                # optional - mathematica

show(ImageSize=600)[source]#

Show a mathematica expression immediately.

This method attempts to display the graphics immediately, without waiting for the currently running code (if any) to return to the command line. Be careful, calling it from within a loop will potentially launch a large number of external viewer programs.

INPUT:

• ImageSize – integer. The size of the resulting image.

OUTPUT:

This method does not return anything. Use save() if you want to save the figure as an image.

EXAMPLES:

sage: Q = mathematica('Sin[x Cos[y]]/Sqrt[1-x^2]')   # optional - mathematica
sage: show(Q)                                        # optional - mathematica
Sin[x*Cos[y]]/Sqrt[1 - x^2]

>>> from sage.all import *
>>> Q = mathematica('Sin[x Cos[y]]/Sqrt[1-x^2]')   # optional - mathematica
>>> show(Q)                                        # optional - mathematica
Sin[x*Cos[y]]/Sqrt[1 - x^2]


The following example starts a Mathematica frontend to do the rendering (Issue #28819):

sage: P = mathematica('Plot[Sin[x],{x,-2Pi,4Pi}]')   # optional - mathematica
sage: show(P)                                        # optional - mathematica mathematicafrontend
sage: P.show(ImageSize=800)                          # optional - mathematica mathematicafrontend

>>> from sage.all import *
>>> P = mathematica('Plot[Sin[x],{x,-2Pi,4Pi}]')   # optional - mathematica
>>> show(P)                                        # optional - mathematica mathematicafrontend
>>> P.show(ImageSize=Integer(800))                          # optional - mathematica mathematicafrontend
