The sufficient example of interpolation is on http://www.gnu.org/software/gsl/manual/html_node/Interpolation.html But you can realize your own minimal and efficient linear interpolation on the grid with given mappings v(i) and i(v). If the mapping i(v) is known, you will not need for lookup of index 'i' by variable 'v', so it will be fast... Michael wrote: > It doesn't seem to be efficient to me?
