NumCosmoMathFitls_fisher

Declaration [src]

void
ncm_fit_ls_fisher (
  NcmFit* fit
)

Description [src]

Computes the covariance matrix using the jacobian matrix and the least squares problem, see ncm_fit_ls_J(). Note that this function uses the gradient defined in the fit object using ncm_fit_set_grad_type() to compute the jacobian matrix.

This function is similar to ncm_fit_fisher() but it computes the covariance using the full jacobian matrix instead adding the individual contributions of each NcmData in the data set.

It sets both the covariance matrix in the NcmFitState object associated to the fit object.
