I want to do 2D interpolation on an irregular grid. In particular, I have a function f:\mathbb R^2 \rightarrow \mathbb R, (x, y) \mapsto z. I have an irregular grid D = (x_i, y_i)_i as well as the corresponding values F = (f_i)_i. I would like to interpolate D, F to obtain f. I have tried Dierckx,…

One more suggestion: try GMT.jl’s splines in tension and see a simple example here.
