2D IFFT in Fortran

[fortek]

Hi,

I'm trying to get the routines c06fuf and c06gcf to calculate the inverse of a 2D FFT.

I've checked my input data in matlab and with normal integration so they should give correct answer. But when I use above routines the oscillations are way to big. The values are oscillating between - to + values instead of 0 to +. Does someone have any tips what I can be doing wrong? Do I need to tweek my input values in some way?

Thanks
