Dear all

Is there a simple and fast way to find the indices of array elements, which
are inside of a boundary (in 2 dimensions). Let's say coord(npoints, 2) is an
array of coordinates in the plane and bound(nbound, 2) is the array of a
bounday polygon. The coordintes are not on a grid (otherwise one could use
polyfillv (PV-Wave).

Thank you for any suggestion!

Martin
