false_conv_tol

False convergence tolerance

Specification

  • Alias: None

  • Arguments: REAL

  • Default: -1. (use NL2SOL internal default)

Description

false_conv_tol (NL2SOL’s xftol) is the false-convergence tolerance (stop with a suspicion of discontinuity when a more favorable stopping test is not satisfied and a step of scaled length at most false_conv_tol is not accepted)

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