Format - of input data is polynomial or we can use name of workspace variable (type of
variable must be polynomial). Polynomials must be monic.
Example
if the plant transfer function is
we have three choice
First we can write in plant box these two polynomials using polynomial function syntax
Second if a(s) and b(s) are workspace variables we can write
Third choice is we can use import menu using context menu or main figure data menu
