[f2py] f2py Arrays and Fortran functions

Hi all,

I am new to f2py and am having some difficulties with array operation. Here
is my design difficulties:

Using python as a glue, I initialize my problem. This involves generating a
series of arrays and matrices. I pass an array and two matrices to FORTRAN
and return an augmented matrix like so:


Python

A1[x],   A2[x,y]   A2[x,z]

pass to FORTRAN        fn(A1,A2,A3)  with intent inout A3

in FORTRAN I have a series of subroutines and functions to preform my
numeric calculations

FORTRAN

subroutine sub(A1,A2,A3,x,y,z)

calculations using A1,A2,A3,x,y,z

call function using data passed from python as in:

function fun(A1,...x,y)

And here is where my problems start.  FORTRAN does not like passing of
Arrays. Solutions I thought of was to make the input data from python GLOBAL
in scope in FORTRAN, but I haven't found any documentation on how to acheive
this either with COMMON or MODULES viz a viz F2PY. Any suggestion would be
appreciated.

Thanks in advance
