Discrete sine transform [message #30565]

Hello all,

I'm another lurker drawn out to ask for help. I think this is more of
a maths question rather than IDL, but as I'm working with IDL and this
seems to be the most friendly newsgroup I know of, I thought I'd try
here!

Does anybody have the algorithm for the discrete sine tranform coded
in IDL. If I understand correctly it can be done (with some
redundency) by using the FFT - but I'm not sure how!

Thanks in advance for your help,

Matt
