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.

Previous version had faulty automatic dimension assignment when the function is called with a single argument.

It has been updated to match diff() defaults for vector, matrix and N-dim arrays.
