Re: [Numpy-discussion] Getting Callbacks with arrays to work

Hi, Thanks all works now! The implicit none only didn't work when defining dv as a function now its a subroutine it seems to work. Regards Jon On 12/01/2010 13:44, Pearu Peterson wrote: Hi, The problem is that f2py does not support callbacks that return arrays. There is easy workaround

[Numpy-discussion] Getting Callbacks with arrays to work

Hi, I'm trying to build a differential equation integrator and later a stochastic differential equation integrator. I'm having trouble getting f2py to work where the callback itself receives an array from the Fortran routine does some work on it and then passes an array back.   For the

Re: [Numpy-discussion] Getting Callbacks with arrays to work

Hi, The problem is that f2py does not support callbacks that return arrays. There is easy workaround to that: provide returnable arrays as arguments to callback functions. Using your example: SUBROUTINE CallbackTest(dv,v0,Vout,N) IMPLICIT NONE !F2PY intent( hide ):: N INTEGER:: N, ic
