Does anyone know where I can get any free 3-D smoothing spline code for irregular data in fortran?
I've used 1-D and 2-D code from Inoue, H., 1986: A least-squares smooth fitting for irregularly spaced data: Finite-element approach using the cubic B-spline basis. Geophysics, 5, 2051–2066.
cheers, arthur
I have a code in Matlab (not spline)

Thanks Mehmet for your kind offer and I hope all is well. I'm trying to find tri-cubic splines in fortran since smooth 2nd-order derivatives are needed in our application; my student and I may rewrite Inoue's code but I'm trying to take the path of least resistance.
Google "tricubic splines fortran" and you will come across Princeton Splines. Haven't got a clue if that's suitable for your purposes.
I just came across this : http://people.sc.fsu.edu/~jburkardt/f_src/pppack/pppack.html
could be smthg for you .
