Member Function Documentation

virtual int fit ( size_t  ndat,
ovector_view &  xdat,
ovector_view &  ydat,
ovector_view &  yerr,
size_t  npar,
ovector_view &  par,
omatrix_view &  covar,
double &  chi2,
param_t &  pa,
fit_funct< param_t > &  fitfun 
) [inline, virtual]

Fit the data specified in (xdat,ydat) to the function fitfun with the parameters in par.

The covariance matrix for the parameters is returned in covar and the value of $ \chi^2 $ is returned in chi2.
