Undefined function 'tf' for input arguments of type 'double'.

I am plotting a pretty simple transfer function to make bode plots magnitude and phase.

code looks something like this

>> num = [1000 10000];

>> den = [1 1100 100000];

>> G = tf(num, den)

>>bode(G), grid

Now, this works and I get the right graphs when I use the online version.

HOWEVER

When I use my PC version I get "Undefined function 'tf' for input arguments of type 'double'."

I'm not sure how to fix this.

You need the Control Systems Toolbox installed.
