grdsample

Interpolates a grid to create a new grid with either: a new grid-spacing, or number of nodes, and perhaps also a new sub-region. Interpolation is bicubic [Default] or bilinear and uses boundary conditions. grdsample safely creates a fine mesh from a coarse one; the converse  may suffer aliasing unless the data are filtered using grdfilter.
