|
|
lmfit - Levenberg-Marquardt least-squares minimization
|
|
|
=head1 DESCRIPTION
|
|
B<lmfit> is a C library for Levenberg-Marquardt least-squares minimization and curve fitting. It is mature code, based on decades-old algorithms from the FORTRAN library MINPACK.
|
|
For fitting a data set {(x_i,y_i)|i=0,1,..} by a parametric curve f(x,t), see B<lmcurve>(3).
|
|
For generic minimization of the Eucledian norm of parametric vector, see B<lmmin>(3).
|
|
For an example how to use B<lmmin>, see the source files I<lmcurve.h> and I<lmcurve.c>. Do not patch these files; copy and modify them to create your own, differently named version of I<lmcurve_data_struct>, I<lmcurve_evaluate>, and I<lmcurve>.
