Paolo Grigis' list of (a few) useful IDL programs.
All programs have the prefix "pg_" to avoid name
conflicts with other programs.
Simple program for plotting a 2-dimensional image with coordinates given by two
one-dimensional (possibnly irregular) vectors x and y. Optionally, log scaling
in both axes is possible.
Computes the cross-correlation between two 2-dimensional arrays (using the FFT
method).
Quadratic fit of the maximum position of an array.
Creates uniform deviates in double precision.
