Parameters estimation constraint in greyest

Hi, I need a help.

Is there a way to use parameter constraint in greyest?

For example, parameters(1) > parameters(2).

So far I just find that we can set the boudary of the parameters.

Thank you in advance

The only constrains you can have on the parameters while using greyest is on the parameters bounds. Unfortunately, as of MATLAB R2022a, you cannot specify boundaries such as parameters(1) > parameters(2).
