Constructor & Destructor Documentation

FunctionFit::FunctionFit	(	ModelFunction &	model_func,
		unsigned int	nvals,
		unsigned int	max_iterations = 500,
		double	tolerance = 1.0e-4
	)

Prepare a non-linear least-square fit of function 'model_func' for 'nvals' values with a maximum of 'max_iterations' iterations and the given 'tolerance'.

Member Function Documentation

bool FunctionFit::fit	(	const Array< float, 1 > &	yvals,
		const Array< float, 1 > &	ysigma = defaultArray,
		const Array< float, 1 > &	xvals = defaultArray
	)

The fitting routine that takes the starting values from the model function, y-values 'yvals', and optionally the corresponding y-error bars 'ysigma' and x-vals 'xvals'. If no error-bars are given, they are all set to 0.1 and if no x-vals are given equidistant points with an increment of one are chosen, i.e. xvals(i)=i; Returns true on success.
