I think your comparison is not really with MATLAB, it looks to me that
you are using the symbolic toolbox, which a while ago was MAPLE and is
now a different 3rd party package (don't remember name).
Your comparisons are a good check whether the scipy results are
correct. But if you want to compare packages, the better analog to
matlab symbolic would be sympy and mpmath.
