fit()

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

Linear fitting routine. Fits the function to the y-values 'yvals', and optionally the corresponding error bars 'ysigma' and x-values 'xvals'. If no error-bars are given they are all set to 1.0 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.

get_function()

Array<float,1> LinearFunction::get_function

(

const Array< float, 1 > &

xvals

)

const

Returns the linear function values for x-values 'xvals' using the current fit parameters.
