Utilize MAXIMA CAS in MATLAB as a symbolic toolbox.

%MAXIMA enables the use of the MAXIMA CAS in MATLAB
% This function uses the Jacomax (Java Connector for Maxima) to start and
% connect to a session of MAXIMA. The user passes the MAXIMA command in as
% a string and the result is returned as a string that can be used in
% conjunction with the vectorize and inline command to construct a function
% that can be evaluated and plotted in MATLAB.
% Required Additional Software:
% 1. Maxima, which is found at:
% 2. Jacomax (Java Connector for Maxima) a basic Java interface for the
% Maxima computer algebra system can be found at:
% The contents of their package must be in java class path
% javaaddpath('jacomax-0.2.3.jar')
% javaaddpath('slf4j-api-1.5.11.jar')
% javaaddpath('jacomax-samples-0.2.3.jar')
% Additionally, you must modify their file to
% point to your installation of MAXIMA and change the file name to be
% Examples:
% result = maxima('expand((x+2)*(x+3))')
% result = maxima('factor(x^2+5*x+6)')
% result = maxima('integrate(x^2+5*x+6,x)')
% result = maxima('diff(x^2+5*x+6,x)')

try this:

 result = maxima('expand((x+2)*(x+3))');
 f = vectorize(inline(result));
