MATLAB Application Program Interface Reference

Set new real data for an mxArray

subroutine mxSetPr(pm, pr)
integer*4 pm, pr

Arguments

Pointer to a full (nonsparse) mxArray.

Pointer to the first element of an array. Each element in the array contains the real component of a value. The array must be in dynamic memory; call mxCalloc to allocate this dynamic memory.

Description

Use mxSetPr to set the real data of the specified mxArray.

All mxCreate calls allocate heap space to hold real data. Therefore, you do not ordinarily use mxSetPr to initialize the real elements of a freshly created mxArray. Rather, you typically call mxSetPr to replace the initial real values with new ones.
