| Post subject: | tricubic spline interpolation? |
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 |
