Point inside/outside a polygon? [message #26180]

Hi all,

Does anyone know of IDL routines for determination of whether a point
datum is inside/outside a closed irregular polygon? I'm told that some
variants of this functionality are available in Matlab and Mathematica,
was curious if anyone had implemented a solution for IDL. My usual
kludge to this is polyfill/mask-based, which is probably a very
inefficient approach...

Thanks,

Dennis Boccippio
