The [[Optimization package]] is missing the functions <tt>lsqcurvefit</tt>, <tt>lsqlin</tt>, <tt>lsqnonlin</tt> to conveniently solve least-squares problems that are nonlinear and/or constrained. | The [[Optimization package]] is missing the functions <tt>lsqcurvefit</tt>, <tt>lsqlin</tt>, <tt>lsqnonlin</tt> to conveniently solve least-squares problems that are nonlinear and/or constrained. Some of the needed algorithms may already be present in the code called by [http://octave.sourceforge.net/optim/function/nonlin_residmin.html <tt>nonlin_residmin</tt>] and [http://octave.sourceforge.net/optim/function/nonlin_curvefit.html <tt>nonlin_curvefit</tt>]. Also, there are free implementations of needed algorithms in other languages, such as [http://www.netlib.org/minpack/ minpack] in Fortran and [http://users.ics.forth.gr/~lourakis/levmar/ levmar] in C. This project would link to or port these implementations and develop Matlab-compatible Octave wrappers. | ||
