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(3). For generic minimization of the Eucledian norm of parametric vector, see B(3). For an example how to use B, see the source files I and I. Do not patch these files; copy and modify them to create your own, differently named version of I, I, and I. =head1 COPYING Copyright (C): 1980-1999 University of Chicago 2004-2015 Joachim Wuttke, Forschungszentrum Juelich GmbH Software: FreeBSD License Documentation: Creative Commons Attribution Share Alike =head1 SEE ALSO =begin html lmcurve(3), lmmin(3) =end html =begin man \fBlmcurve\fR(3), \fBlmmin\fR(3) .PP =end man Homepage: http://apps.jcns.fz-juelich.de/lmfit =head1 BUGS Please send bug reports and suggestions to the author .
