msize

 PURPOSE: calculate total number of elements of a n-dimensional matrix.
          This is exactly what numel() does, only I didn't know before...
 ------------------------------------------------------------------------
 USAGE: s = msize(M)
 where: [M] is the Matrix to calculate no of elements for
-------------------------------------------------------------------------
 OUTPUTS:
        [s] size in cells (total number of elements)
 ------------------------------------------------------------------------

 See also: size(), numel()
