absolute_conv_tol


Absolute convergence tolerance

Specification

Alias: none

Argument(s): REAL

Default: -1. (use NL2SOL internal default)

Description

absolute_conv_tol (NL2SOL's afctol) is the absolute function convergence tolerance (stop when half the sum of squares is less than absolute_conv_tol, which is mainly of interest on zero-residual test problems).

The internal default is a function of machine epsilon (as limited by function_precision). The default is selected with a value of -1.
