LMFitter object is an ActiveX wrapper for the popular levmar code written by Manolis
Lourakis. As well as "native" DMFitter, LMFitter coclass
included into the fitter.dll unit allows to use this implementation of famous Levenberg-Marquardt
curve fitting algorithm in thousands of ActiveX-enabled applications. Both coclasses
implement the same interfaces so that you may easily exchange both versions.
Notice that LMFitter is just a wrapper, while the LM fitting engine itself is
written in C++ and stored in a separate DLL (lmhelper.dll) which should be available
in the installation folder.
