I've been fitting simple models containing few gaussians to my
experimental data using E. Grossmann's downsimplex (Nelder-Mead
polytope) function. It can be found somewhere under
http://octave.sourceforge.net/
Convergence of the algorithm is good enough, if you supply initial
parameter values which are close to the "right" values. Gradient based
methods would probably be better when fitting analytical functions though,
has anyone written any code for this?
