set_method_opt

sherpa.ui.set_method_opt(optname, val)

Set an option for the current optimization method.

This is a helper function since the optimization options can also be set directly using the object returned by get_method.

Parameters:

• optname (str) – The name of the option to set. The get_method and get_method_opt routines can be used to find out valid values for this argument.
• val – The new value for the option.

Raises:

sherpa.utils.err.ArgumentErr – If the optname argument is not recognized.
