Anyone know how to get the coefficients out of the Bicubic2D function? Or if you have a program that does the equivalent that would work for me. I find myself needing to port the fit into excel and am finding I don't know how to do that.
A 4.0 example attached but any example will work.
Thanks,
According to the help the algorithm used in Prime is based on the one published in the numerical recipes:
The Bicubic2D function is based on SPLIN2 (p.128) from the book "Numerical Recipes in C, The Art of Scientific Computing" (Cambridge University Press), Copyright (C) 1987, 1988 Numerical Recipes Software, and is used under license.
So you may re-create the function by looking up the algorithm in the online e-book -> http://numerical.recipes/book/book.html
