Hi, I have been using the fantastic grid package by Tim Holy for the past while but I really need to allow for a non-equally spaced grids. It is important to have a bunch of points at some parts of the grid but not at others. I was wondering if anyone knows of any package that allows for irregular interpolation. I know it is possible to do this using Tim's package for one dimension but I want to interpolate in 3 dimensions. Has there been any new packages developed lately or does anyone know a fast way to do this?
Thank you
