when I try to use tf function this is what I get :
>> s = tf('s')
Unrecognized function or variable 'tf'.
Did you mean:
>> s = tfe('s')

It seems that the Control system toolbox is not installed !
You have to install It first !

You need to have the control system toolbox: https://www.mathworks.com/help/control/index.html for using tf() function. It seems that you haven't installed this toolbox. Check the output of
ver control
If you have the toolbox installed, it will display the version of toolbox otherwise you don't have the toolbox.
