mxCopyReal8ToPtr (Fortran)

Copy REAL*8 values from Fortran array to pointer array

Fortran Syntax

mxCopyReal8ToPtr(y, px, n)
real*8 y(n)
mwPointer px
mwSize n

Arguments

y

REAL*8 Fortran array

px

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

n

Number of elements to copy

Description

mxCopyReal8ToPtr copies n REAL*8 values from the Fortran REAL*8 array y into the MATLAB array pointed to by px, either a pr or pi 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.

Examples

See matdemo1.F and 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.
