[Help-gsl] Mixed-Radix FFT problems

I have been able to get the Radix-2 FFT to work just fine.
When I try to use the Mixed-Radix FFT for some values of n I
get a correct transformation, but for others I only get
maybe 1 frequency component or nothing at all, it's quite
random. It does not say in the documentation if you are
suppose to zero-pad your data until a multiple of 2 is
reached, but that is the only way I can see getting the
Mixed-Radix to work. Any suggestions?
Thank you.
