How do I find the Step Response of a system to a an input that is not a Unit Step?

I am aware of the STEP function in the Control Systems Toolbox. However, the STEP function works only for unit step inputs. I would like to know if there is any other function that will work for inputs other than unit step inputs.

To find the step reponse of a system to an input that is not a unit step, you can use the LSIM function that ships with the Controls Toolbox. LSIM can be used to simulate reponses to any arbritary input.

For more information about this function, type either of the following at the MATLAB prompt:

doc lsim

or

help lsim
