stepinfo()
S = STEPINFO(Y,T,YFINAL) takes step response data (T,Y) and a steady-state value YFINAL and returns a structure S containing the following performance indicators:
* RiseTime: rise time
* SettlingTime: settling time
* SettlingMin: min value of Y once the response has risen
* SettlingMax: max value of Y once the response has risen
* Overshoot: percentage overshoot (relative to YFINAL)
* Undershoot: percentage undershoot
* Peak: peak absolute value of Y
* PeakTime: time at which this peak is reached.
