Get the number of bytes required to store each data element
Fortran Syntax
Arguments
Returns
The number of bytes required to store one element of the specified mxArray, if successful. Returns 0 on failure. The primary reason for failure is that pm points to an mxArray having an unrecognized class. If pm points to a cell mxArray or a structure mxArray, then mxGetElementSize returns the size of a pointer (not the size of all the elements in each cell or structure field).
Description
Call mxGetElementSize to determine the number of bytes in each data element of the mxArray. For example, if the class of an mxArray is int16, then the mxArray stores each data element as a 16-bit (2 byte) signed integer. Thus, mxGetElementSize returns 2.
