However, if you change the Variable to 'z^-1' (or 'q')by

set(h,'Variable','z^-1'),

the same command

set(h,'num',[1 2],'den',[1 3 4])

now interprets the row vectors [1 2] and [1 3 4] as the polynomials

and and produces:

Note Because the resulting transfer functions are different, make sureto use

the convention consistent with your choice of variable.
