This should be easy for anyone who knows this program. How do you create a transfer function on Matlab7? It used to be T=tf(num,den) but now that doesnt work. I know its a stupid question but i just cant find the answer. Also does any one know how to create a variable that stays a variable? for example it used to be (i think) vars x. but now i cant use a global or local variable without setting it equal to a integer. Thanks for any help.
