Re: [f2py] FW: Pass a python array on a subroutine

Hi,

Here is a simple example that works for me... perhaps if you check
this works for you you will see if you're f2py is working properly.
Then you can start to add things from your full code to see where the
problem is. I think you need to be careful with indexes - one thing is
that in your EXECUTABLE function it looks like they are the wrong way
round - val is (b,c) but you are looping (1..c, 1..b).

I put this in a function called testpass.f95
!---
subroutine executable(val, b, c)
    implicit none
    integer, intent(in) :: b,c
    real, dimension(b,c), intent(in) :: val
    integer :: li,co

    DO li = 1,b
        DO co = 1,c
            WRITE (*,*) val(li, co)
        END DO
    END DO
end subroutine
!---
and run f2py -c testpass.f95 -m testpass
Then from ipython:
In [2]: import testpass
In [3]: x = np.random.rand(3,4)
In [4]: testpass.executable(x)
  0.4249328
  0.5246207
  0.4804753
  0.5709109
  0.7447789
  0.3164150
  0.6302102
  0.7069213
  0.1635373
  2.3983051E-03
  0.8255721
  0.7564080

I hope this helps

Robin
