Fast Cosine Transform Routine [message #11824]

Hi,

I use IDL a lot and currently have the need to perform 2D cosine transforms.
I have implemented this using the FFT command in IDL. (How to do a cosine
transform using the FFT is described in "Numerical Recipes in C"). I am not
happy with this approach and would prefer to use a more direct method. I can
code the cosine transform into IDL but first I would like to see if anyone
knows of an IDL routine that already exists for 2D cosine transforms.

Thanks
