Two dimensional cubic spline interpolation
Dear all:
I want to interpolate a given function f(x,y) on a two dimensional grid. I have the values of funtion on grid points. I want to interpolate the value of funtion, its fist derivative w.r.t x and y, its second drivative w.r.t. x and y, and mixed derivative at a known point in the grid. Is there any good reference or test code?Please help me. thanks you!

I don't happen to be up to date anymore, but maybe you can find something at:
http://www.nr.com/ Or on the free online part: http://www.nrbook.com/a/bookfpdf/f36.pdf It's good old Fortran 77 and includes a short explanation about how stuff works. 
Interpolating splines in 3D space
Hello every one
I want to interpolate a given points(x,y,z) on a three dimensional grid by fortran or C++. Can anyone point to me about the interpolating splines in 3D space coding procedure by FORTRAN or C++. Thanks
