This small example G program will show you how to deal with polynomial matrices. I have created a small library of vi's to cope with multivariable
FIR systems ie Polynomial Matrices of the form
This example is just a second order example where n=2 and the matrices are all 2X2.
I put a unit step u=[1 1] into this type of system and view the steady-state output.
Is useful in all manner of control and signal processing systems which use multivariable filters.
