why not use Matlab code analyzer?

2: Parse error at '=': usage might be invalid MATLAB syntax.
3: Variable 'vp' might be set by a nonscalar operator.
4: Variable 'vp' might be set by a nonscalar operator.
5: Terminate statement with semicolon to suppress output (within a script).
7: Terminate statement with semicolon to suppress output (within a script).
10: Variable 'vp' might be set by a nonscalar operator.
