[comp.sources.wanted] I need help interpolating F

 [].

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
