SYSTEM - @subst

[tvonbrasch]

Hi

How can I retrieve the specifications in a SYSTEM object with the coefficients substituted into the string specification? I used the command

Code: Select all

SYSTEM.@subst

however, this command wrongfully substituted the current values in the coefficient vector C into the specification (and not the coefficient values in the system ) ....

If there is a command that retrieves the specification with substituted coefficients for all type of objects, that would be great.

Is there a command for retrieving the specification for a variable in a model with substituted coefficients if the variable comes from a system, equation object etc?

Hello,

I'm not sure if System::@subst's behavior is more a bug or a feature, but you can use System::updatecoefs followed by System::@subst to achieve the specification you want, at least until I correct @subst's behavior.

okay. your solution is great Matt, thanks. this works for me now. ideally, I would also like to have a command that retrieves the coefficient values from a specification in a model object. hopefully, this is something you can add to EV12 if it does not already exist.

The next patch will change System::@subst and Logl::@subst to use the estimated coefficients as intended.

Okay, great
