It is mature code, based on decades-old algorithms from the FORTRAN library MINPACK.</p> 25 26<p>For fitting a data set {(x_i,y_i)|i=0,1,..} by a parametric curve f(x,t), see <b>lmcurve</b>(3).</p> 27 28<p>For generic minimization of the Eucledian norm of parametric vector, see <b>lmmin</b>(3).</p> 29 30<p>For an example how to use <b>lmmin</b>, see the source files <i>lmcurve.h</i> and <i>lmcurve.c</i>.
