Global fitting session [0 .. 14]
1. al_nleqsolve point select equalities
valid for noisy data via user piecewise linear.
2. Levenberg-Marquardt: generally valid [fails Frechet]
3. Cholesky matrix solver ... solves all, faster
model function(s) parameters, linfit components,
remarkable linfitCheby, polyorder, direct discrete data.
............................ rational fraction.
EMERITUS => Conjugate gradient Minimize(init,iter)

Hola Jean

This is my best setting for "Genfit_10 Frenchet" in SS-6179
with LM using 6 data, since an out of memory error occurs using all data.

SS-7251 solves it without any problem with all the data.

Thanks Grand Doctor Carlos ...
So, my native SS 6179 suffers numerical issue
that SS 7251 cures in your SS 6179 ... Ah !
LMSA in native SS 6179 takes much higher TOL [typical 0.0001/0.00001]
