mxGetData

Get pointer to data

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.
