Re: [f2py] Dynamic Arrays in f2py

Yes, I tried it. But i dont want to use global variables, and when i try to pass them as a parameter:

  integer, allocatable :: indx(:) !outgoing parameter
                             1
Error: ALLOCATABLE attribute conflicts with DUMMY attribute at (1)



 
Hi,

Have you considered using allocatable arrays? See, for example,
