Function: maxima

Purpose

Execute a function with several arguments in Maxima and retrieve result.

Synopsis

[sym] = maxima(function,arg1,arg2,...)

Description

Use restricted to Maxima functions returning a single symbolic object, otherwise a string is returned instead of a sym-object. Type mhlp name_of_maxima_function for a description of the Maxima function.

Note that, when the result is not as expected, the function str2max2sym invoked with option 'vec' might be complementary for understanding the problem. In case of unrecoverable problem invoke the function restartserver in order to re-initialize Maxima.

Input arguments

function String: name of a Maxima function

arg1, arg2 Strings, sym-objects or syml-objects: arguments of the Maxima function. Note that syml-objects have been implemented specifically for the function maxima as some Maxima functions require input arguments defined as lists rather than matrices.

Output argument

sym Symbolic object.

EXAMPLES
   x = maxima('factorsum','a*x*z+a*z+a*w*x+v*x+u*x+a*w+v+u')

   p1=sym('-a*b^2-3*b^2+a^2*b+3*a*b+3*b+a^2+a');
   p2=sym('-a*b^3-3*b^3-a*b^2+a^3*b+3*a^2*b+a*b+3*b+a^3+a');
   maxima('gcd',p1,p2)

   p=sym('a^2*b^2-3+a*b*(a-b)*b^6');
   maxima('scsimp',p,'a=b')

   p=maxima('solve',syml(['a*x+b*y=3','a*x*y = 2']),syml(['x','y']))
   p.x
