Tolerances and fundamental constants. Sets the various accuracy cut-offs, constants and tolerances used throughout Spinach kernel.
Contents
Syntax
spin_system=tolerances(spin_system,sys)
Arguments
spin_system - Spinach system description object sys - system specification object described in the input preparation section of the manual
Outputs
spin_system - updated system description object
Notes
Direct calls and modifications to this function are discouraged: the accuracy settings should be modified by setting the sys.tols structure, see the input preparation manual.
