This subroutine processes the nonlinear Levenberg-Marquart algorithm and returns the one-dimensional array params at a given iperp. The variable quality is the sum of the squares of all residuals.


Type IntentOptional Attributes Name
integer, intent(in) :: is

Index of species for which LM_nonlinear_fit is executed.

double precision, intent(in) :: g(0:npar)

Array of function to be fitted.

integer, intent(in) :: n_params

Total number of fit parameters for a given species.

integer, intent(in) :: nJT

First dimension of matrix JT (see determine_JT).

double precision, intent(inout) :: params(n_params)

Array of fit parameters.

logical, intent(in) :: param_mask(n_params)

Bit mask for required fit parameters.

integer, intent(in) :: iperp

Index of perpendicular momentum.

integer, intent(in) :: npar

Number of steps in parallel momentum

integer, intent(in) :: ipparbar_lower

Lower index of parallel momentum (relativistic).

double precision, intent(out) :: quality

Quality of the individual fit result.
