mxCopyInteger4ToPtr (MATLAB Application Program Interface)

Copy INTEGER*4 values from a Fortran array to a pointer array

Fortran Syntax

subroutine mxCopyInteger4ToPtr(y, px, n)
integer*4 y(n)
integer*4 px, n

Arguments

y
INTEGER*4 Fortran array.

n
Number of elements to copy.

px
Pointer to ir or jc array.

Description

mxCopyInteger4ToPtr copies n INTEGER*4 values from the Fortran INTEGER*4 array y into the MATLAB array pointed to by px, either an ir or jc array. This subroutine is essential for use with Fortran compilers that do not support the %VAL construct in order to set up standard Fortran arrays for passing as arguments to the computation routine of a MEX-file.

Note: This function can only be used with sparse matrices.
