I am running R2012b.
I type in: s = tf('s')
Undefined function 'tf' for input arguments of type 'char'.
can someone please help me?
Thanks so much!
tf is part of Control System Toolbox. The error message you are seeing means you do not have this product on your license. You can see which toolboxes you have by typing
