Re: Regridding based on other arrays

Richard,

"To grid a set of (X, Y, value) triples onto a grid of specified resolution,
sometimes called Objective analysis,  use one of the family of "scat2grid"
external functions.  See the description of these functions in Appendix A
starting at p. 68."

You should also be aware that you can plot your data in it's native grid using
the 3-argument SHADE, FILL and CONTOUR commands:
