mxCopyPtrToReal8 (Fortran)

Copy REAL*8 values from pointer array to Fortran array

Fortran Syntax

mxCopyPtrToReal8(px, y, n)
mwPointer px
real*8 y(n)
mwSize n

Arguments

px

Pointer to the real or imaginary data of a double-precision MATLAB^® array

y

REAL*8 Fortran array

n

Number of elements to copy

Description

mxCopyPtrToReal8 copies n REAL*8 values from the MATLAB array pointed to by px, either a pr or pi array, into the Fortran REAL*8 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.

Examples

See fengdemo.F in the eng_mat subdirectory of the examples directory for a sample program that illustrates how to use this routine in a Fortran program.
