How to create an interpolation on an unstructured grid …

WebFor 2-D interpolation, where xq and yq specify an m-by-n grid of query points, vq is an m-by-n array. For 3-D interpolation, where xq, yq, and zq specify an m-by-n-by-p grid of query points, vq is an m-by-n-by-p array. If xq, yq, (and zq for 3-D interpolation) are vectors that specify scattered points, then vq is a vector of the same length.
