mxCopyPtrToInteger4 (MATLAB Application Program Interface)

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

subroutine mxCopyPtrToInteger4(px, y, n)
integer*4 y(n)
integer*4 px, n

Arguments

n
Number of elements to copy.

px
Pointer to ir or jc array.

y
INTEGER*4 Fortran array.

Description

mxCopyPtrToInteger4 copies n INTEGER*4 values from the MATLAB array pointed to by px, either an ir or jc array, into the Fortran INTEGER*4 array y. 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.
