ROOT::Math::FitTransformFunction< FMFunc > Class Template Reference

template<class FMFunc>
class ROOT::Math::FitTransformFunction< FMFunc >

Internal class used by GSLNLSMinimizer to implement the transformation of the chi2 function used by GSL Non-linear Least-square fitting The class is template on the FitMethodFunction type to support both gradient and non gradient functions.
