[SciPy-user] [f2py] hide ?

Here are some things that could be wrong.

1. You declare a as intent(in, out), this means that a is modified in place,
ie, the subroutine does not return a value.
>>> essai.essai(a, b, KW, nx, ny, nz)
will hence return none.

2. Declare the dimension explicitely in the cf2py comments
cf2py integer dimension(nx,ny,nz), intent(in) :: b

3. If you want to hide the shape integers, you need to tell it to.
cf2py integer, intent(hide) :: nx=shape(b,0)
cf2py integer, intent(hide) :: ny=shape(b,1)
cf2py integer, intent(hide) :: nz=shape(b,2)

My advice would be to start with the plain fortran function without cf2py
comments, and add them one at a time.
