It probably means you not have the Control System Toolbox. Use the ver command to see if you havethe toolbox
ver
or see the output of the following

which tf

IF the license the University license includes the Controls Toolbox and your University email id is authorized to be added to the license. I manage a license for a University and we have to add users email ids to be associated with the accounts or get product key to associate licenses to accounts. If we need extra toolboxes we pay for them to be added to our license.

It seems that your function is not defined.
e.g. try something like this to define a function
impuls= @(x,y) x+y
