.help nlstat Feb91 "Nlfit Package" .ih NAME nlstat[ird] -- get an NLFIT parameter .ih SYNOPSIS include [ird]val = nlstat[ird] (nl, parameter) .nf pointer nl # curve descriptor int parameter # parameter to be returned .fi .ih ARGUMENTS .ls nl The pointer to the curve descriptor structure. .le .ls parameter Parameter to be return. Definitions in nlfit.h are: .nf NLNPARAMS integer # Number of parameters NLNFPARAMS integer # Number of fitted parameters NLITMAX integer # Maximum number of iterations NLITER integer # Current number of iterations NLNPTS integer # Number of points NLSUMSQ real/double # Current reduced chi-squared NLOLDSQ real/double # Previous reduced chi-squared NLLAMBDA real/double # Value of lambda factor NLTOL real/double # Fitting tolerance in %chi-squared NLSCATTER real/double # Mean scatter in the fit .fi .le .ih DESCRIPTION The values of integer, real or double parameters are returned. The parameters include the number of parameters, the number of fitted parameters, the maximum number of iterations, the number of iterations, the total number of points, the current chi-squared, the previous chi-squared, the lambda factor, the fitting tolerance and the fitted scatter term. .ih EXAMPLES .nf include int nlstati() call malloc (buf, nlstati (nl, NLNPARAMS), TY_REAL) call nlpgetr (nl, Memr[buf], nparams) .fi .ih SEE ALSO nlpget .endhelp
