These routines provide a high level wrapper that combine the iteration and convergence testing for easy use.
This function iterates the solver s for a maximum of maxiter
iterations. After each iteration, the system is tested for convergence
using gsl_multifit_test_delta
with the error tolerances epsabs
and epsrel.
These functions iterate the solver s for a maximum of maxiter
iterations. After each iteration, the system is tested for convergence
with the error tolerances xtol, gtol and ftol.
Upon successful convergence,
the function returns GSL_SUCCESS
and sets info to
the reason for convergence (see gsl_multifit_fdfsolver_test
).
Otherwise, the function returns GSL_EMAXITER
indicating
the system did not converge after maxiter iterations.
