Set up a model object to use either scalar or custom tolerances

Call use_custom_tol() to use custom relative and absolute tolerances in a model; call use_scalar_tol() to revert to the traditional configuration where a single rtol and atol are applied to all compartments.

use_custom_tol(x)

use_scalar_tol(x)

Arguments

x

a model object.

Value

An updated model object.

Details

If customized tolerances have not been initialized yet, they will be, assigning the current rtol or atol for every compartment. These default values can be updated using custom_rtol(), custom_atol(), or custom_tol().
