Class of array as string
Call mxGetClassName to determine the class of an mxArray. The class of an mxArray identifies the kind of data the mxArray is holding. For example, if pm points to a logical mxArray, mxGetClassName returns logical.
mxGetClassID is like mxGetClassName, except that the former returns the class as an integer identifier, as listed in the mxClassID reference page, and the latter returns the class as a string, as listed in the mxIsClass reference page.
