Hi all,

I'm looking to do tricubic spline interpolation on some gridded data I have - is this something ALGLIB currently supports? The documentation confused me - eg. the "spline3dcalc" function says it will take tricubic splines - however it appears the coefficient table which needs to be passed in comes from "BuildBicubicSpline" etc. (ALGLIB 3.10). Any help would be much appreciated, thanks!

Jack

Hi!

No, there only exists trilinear interpolation. It is performed by alglib::spline3dbuildtrilinearv() function
