This describes a fit function that is used to fit data to any functional form.

A fit function is used to describe a set of data \(y_k, k = 1 ... M\), which are collected as a function of one or more independent variables \(x\) at the points \(x_k\). The fit function \(f\) describes these data in an approximative way as \(y_k \approx f(a_0, . . . a_n, x_k)\), where \(a_i, i = 0 . . . n\) are the fit parameters (which are stored the instances of NXfit_parameter).
