mxCopyPtrToReal4

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

Fortran Syntax

• subroutine mxCopyPtrToReal4(px, y, n)
  real*4 y(n)
  integer*4 px, n
  

Arguments

px
   Pointer to the real or imaginary data of a single-precision MATLAB array.

y
   REAL*4 Fortran array.

n
   Number of elements to copy.

Description

mxCopyPtrToReal4 copies n REAL*4 values from the MATLAB array pointed to by px, either a pr or pi array, into the Fortran REAL*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.
