mxCopyPtrToReal8 (MATLAB Application Program Interface)

Copy REAL*8 values from a pointer array to a Fortran array

subroutine mxCopyPtrToReal8(px, y, n)
real*8 y(n)
integer*4 px, n

Arguments

n
Number of elements to copy.

px
Pointer to pr or pi array.

y
REAL*8 Fortran array.

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.
