[]. I am looking for code, preferably in FORTRAN, or references to code, or a cookbook description for an algorithm, to do interpolation for a function F(x,y,z) of three variables, given F tabulated on a regular, i.e. xl,(dx),xh; yl,(dy),yh; zl,(dz),zh, grid. The F that I am immediately concerned with is nicely continuous and smooth, but I may want to handle Fs that are less well behaved. The IMSL subroutine package has routines IBCCCU,IBCEVL and IBCIEU to do BiCubic spline interpolation for functions G(x,y) of two variables, but there is nothing for three variables. Thank you in advance Rostyk -- Reply-To: Rostyslaw Jarema Lewyckyj urjlew@ecsvax.UUCP , urjlew@tucc.bitnet or urjlew@tucc.tucc.edu (internet)
