Linear system scaling method

Type : Selection

Range : The settings listed below

Default : None

This option determines the method used to compute symmetric scaling factors for the augmented system (see also the option Linear System Scaling ). This scaling is independent of the NLP problem scaling. By default, MC19 is only used if MA27 or MA57 is selected as linear solver as controlled by the option Linear Solver Selection . Possible values are:

• None

• MC19

Note

• This option is only used if the user has provided a DLL with HSL subroutines.
