Member Function Documentation

§ 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.
