6 lmfit - Levenberg-Marquardt least-squares minimization
7
9 lmfit is a C library for Levenberg-Marquardt least-squares minimization
10 and curve fitting. It is mature code, based on decades-old algorithms
11 from the FORTRAN library MINPACK.
12
13 For fitting a data set {(x_i,y_i)|i=0,1,..} by a parametric curve
14 f(x,t), see lmcurve(3).
15
16 For generic minimization of the Eucledian norm of parametric vector,
17 see lmmin(3).
18
19 For an example how to use lmmin, see the source files lmcurve.h and
20 lmcurve.c. Do not patch these files; copy and modify them to create
21 your own, differently named version of lmcurve_data_struct,
22 lmcurve_evaluate, and lmcurve.
