mxSetImagData (C and Fortran) - Set imaginary data pointer for mxArray
C Syntax
#include "matrix.h"
void mxSetImagData(mxArray *pm, void *pi);
Fortran Syntax
mxSetImagData(pm, pi)
mwPointer pm, pi
Arguments
- pm
Pointer to an mxArray
- pi
Pointer to the first element of an array. Each element in the
array contains the imaginary component of a value. The array must
be in dynamic memory; call mxCalloc to allocate
this dynamic memory. If pi points to static memory,
memory errors will result when the array is destroyed.
Description
mxSetImagData is similar to mxSetPi,
except that in C, its pi argument is a void
*. Use this on numeric arrays with contents other than double.
This function does not free any memory allocated for existing
data that it displaces. To free existing memory, call mxFree on
the pointer returned by mxGetImagData before
you call mxSetImagData.
