Fortran Syntax

integer*4 function mxGetData(pm)
integer*4 pm

Arguments

pm
Pointer to an mxArray.

Returns

The address of the first element of the real data, on success. Returns 0 if there is no real data or if there is an error.

Description

Call mxGetData to get a pointer to the real data in the mxArray that pm points to. To copy values from the pointer to Fortran, use one of the mxCopyPtrTo* functions in the manner shown here.

C      Get the data in mxArray, pm
       mxCopyPtrToReal8(mxGetData(pm), data, 
     +                      mxGetNumberOfElements(pm))

mxGetData is equivalent to using mxGetPr.
