circular diff

diff with wrap-around differences, same sized output matrix

You are now following this Submission

difc is a wrapper for matlab's diff() and takes the same arguments.

The returned matrix size is the same as the input matrix size, like matlab's gradient().

Higher N works using recursion.
Zero N returns the input matrix.
