Change in the sequence of evaluation, or failure to clear variables.

Differences between the Professional and Student Versions

EXAMPLE:

Some commands that work correctly in the Professional Version of MATLAB
may not work in the Student Version. Here is an example from MATLAB
Release 11:
>> syms p t
>> ezsurf(sin(p)*cos(t), sin(p)*sin(t), cos(p), ...
[0, pi, 0, 2*pi]); axis equal
This correctly plots a sphere (using spherical coordinates) in the Professional
Version, but in the Student Version you get strange error messages such as
??? The , maple , function is restricted in the
Student Edition.
