set_method_opt

Context: methods

Synopsis

Set an option for the current optimization method.

Syntax

set_method_opt(optname, val)

optname - str

Description

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


Example

Change the maxfev parameter for the current optimizer to 2000.

>>> set_method_opt('maxfev', 2000)

PARAMETERS

The parameters for this function are:

Parameter Definition
optname 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.

Bugs

See the bugs pages on the Sherpa website for an up-to-date listing of known bugs.
