The signal processing capabilities of packages such as MATLAB are glaringly
missing from IDL. Why don't we users write our own signal processing toolkit
as a set of IDL .pro files? Research Associates Inc supports this kind of
activity through their user library files.

I have written two .pro files for IIR filtering called in a similar manner to the
MATLAB filter.m and filtfilt.m files. Send mail to ritscher@crd.ge.com if you
would like me to mail you these.

Have others written signal processing routines that are in a condition ready to
be shared? If so, please send mail to me, or post their availability to this
news group or to comp.lang.idl.
