Fitter is a C++ program aimed to fit a chosen theoretical multi-parameter function through a set of data points. The method of fitting is chi-square minimization. Moreover, the robust fitting method can be applied in Fitter. Fitter was disigned to be used for a small-angle neutron scattering data analisis. Respective theoretical models are implemented in it. Some commonly used models (gaussian and polynomials) are also implemented for wider applicability.
