Hi all, I have been looking at Interpolations.jl, GridInterpolation.jl Diereckx.jl and a few additional packages to solve irregular interpolations in 2D. Maybe this is a trivial question, but any help would be much appreciated.
Assume I have a collection of irregularly spaced 2D points (x,y) and an additional value z for each of these that I would like to interpolate over. Essentially, I have a all x coordinates in a n x m matrix, all y coordinates in another n x m matrix and all z values - you guessed it - also in a n x m matrix. I would like to interpolate the z values onto another set of x,y coordinates, but can't seem to figure out what would be the right approach here. Should I just manually find closest neighbors for each x,y,z coordinate and interpolate locally or could any of the existing interpolation package. Thanks!
