Yes, pcolormesh and pcolor use the same argument parsing and checking. 
They actually *want* N+1, M+1; the *acceptance* of N, M is a matlab-ism 
that is convenient for quick looks, but is also a potential source of error.

The OP has an X dimension of M+2, which indicates an error earlier in 
the OP's code.
