In fact I am looking for some extra libraries dealing with the folowing subjects : - data smoothing (for 0 to 3-rd order Lagrange, or other) - signal derivative - minimization techniques for fitting signals with complex functions (Marquardt-Levenberg, Gradient Descent, or other) Of course, it needs to be as fast as possible. I am working with an IBM rs6000-aix machine. (Unix) If I can't find those things, I might write them in GNU C++ because it's very fast. Unfortunatly, my own Octave '.m' programs seem too slow. The only possibility to increase speed is I guess to compile it as Octave libraries. Thanks. Emmanuel FARHI.
