It is mature code, based on decades-old algorithms from the FORTRAN library MINPACK. 17 18For fitting a data set {(x_i,y_i)|i=0,1,..} by a parametric curve f(x,t), see B<lmcurve>(3). 19 20For generic minimization of the Eucledian norm of parametric vector, see B<lmmin>(3). 21 22For 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>. 23 24=head1 COPYING 25 26Copyright (C): 27 1980-1999 University of Chicago 28 2004-2015 Joachim Wuttke, Forschungszentrum Juelich GmbH 29 30Software: FreeBSD License 31 32Documentation: Creative Commons Attribution Share Alike 33 34 35=head1 SEE ALSO 36 37=begin html 38 39<a href="http://apps.jcns.fz-juelich.de/man/lmcurve.html"><b>lmcurve</b>(3)</a>, 40<a href="http://apps.jcns.fz-juelich.de/man/lmmin.html"><b>lmmin</b>(3)</a> 41 42=end html 43 44=begin man 45 46\fBlmcurve\fR(3), \fBlmmin\fR(3) 47.PP 48 49=end man 50 51Homepage: http://apps.jcns.fz-juelich.de/lmfit 52 53=head1 BUGS 54 55Please send bug reports and suggestions to the author <j.wuttke@fz-juelich.de>. 56
