§ fit()

virtual bool FunctionFitInterface::fit ( const Array< float, 1 > &  yvals,
const Array< float, 1 > &  ysigma = defaultArray,
const Array< float, 1 > &  xvals = defaultArray,
unsigned int  max_iterations = DEFAULT_MAX_ITER,
double  tolerance = DEFAULT_TOLERANCE 
)
pure virtual

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; A maximum of 'max_iterations' iterations and the given 'tolerance' is used during the fit. Returns true on success.

Implemented in FunctionFitDownhillSimplex, and FunctionFitDerivative.

§ init()

virtual bool FunctionFitInterface::init ( ModelFunction model_func,
unsigned int  nvals 
)
pure virtual

Prepare a non-linear least-square fit of function 'model_func' for 'nvals' values

Implemented in FunctionFitDownhillSimplex, and FunctionFitDerivative.
