integration - 1 direction

We try since one week to perform Fourier's transform of a spatial-function along the direction "z" only.
We mean, we have a function f(x,y,z) first performed by COMSOL (it is the solution of a PDE...) depending on the spatial variables x, y, z. We would like to obtain Fourier's transform of this function only along the z-direction [i.e. f(x,y,z)-------TF------> f(x,y,q) = \int_{-infinity}^{+infinity} f(x,y,z)*exp(q*z) dz ].
- COMSOL can perform this calculation ? I think that I have to draw a new axis "z" (to perform this integration) but really I do not know how draw this axis from - infinity to + infinity !!
- Have you some solutions to perform this calculation ? Unfortunately this problem is not treated in COMSOL's book.
Thank you for your help !

Thus, I restarted the discussion now hoping an answer this time...
