X-convergence tolerance


Alias: none

Argument(s): REAL

Default: -1. (use NL2SOL internal default)


x_conv_tol maps to the internal NL2SOL control xctol. It is the X-convergence tolerance (scaled relative accuracy of the solution variables).

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