Do you have a function named “y.m” somewhere in your Matlab path?

I have the same problem now,have you solved it now? can you tell me how

Do make sure you’re using the latest version of MATLAB (whether v2.1 or 3.0beta). And also do make sure that you do not have any MATLAB functions in your path with single-letter names like x.m or y.m.

I just found a function named y.m,thank you very much.
