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

Thank you both for you help.

q and r are the number of lines and columns. I just forget to replace it by c and b in the subroutine execute.
Now, I specify intent(in) and I called the subroutine just with Proj as parameter but values are still nulls and the number of lines and column is not correct anymore.
This code compile file. 
ecriproj() is needed in order to write the values in a binary file.
