system - zero restrictions

Postby tvonbrasch » Mon Jun 16, 2014 1:58 am

Hi

I have made a system from a pool object using the makesystem command. I want to impose zero restrictions on many of the coefficients. How can I program these zero restrictions? Do I have to use the @svectornb command, replace the coefficients with zeroes and then make a new system, or is it another way of replacing coefficients in a system object?

Just replace the coefficients with zero in the system specification.

but how do I program it? i want to make a program where this operation is a part of the procedure, and I do not want to do it manually. is there a way of doing this easily within a program?

Not easily, no. You'd have to modify the text by searching for the coefficient strings. Complicated.
