mxCopyReal8ToPtr

Copy REAL*8 values from Fortran array to pointer array

Fortran Syntax

• subroutine mxCopyReal8ToPtr(y, px, n)
  real*8 y(n)
  integer*4 px, 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(y,px,n) 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.

Example

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.
