I have developed a model in simulink. I am using "simout" to get the data in Matlab so that I can plot the data from simout using matlab plot command with some other data from m file code. However I want to find the system response characteristics for this data from simulink. Say for e.g. when I plot simout then I want to find out rise time, settling time, percentage overshoot looking at the waveform plot of the data. How can I do this ? I know that when you build a state space using sys function then you can plot the step system response using command step(sys) and this plot reads the characteristics. However I want to do this for any data I have in array format. I might have got that data from simulink or some m file processing. Is there some function which takes in data arrays and may be time array and gives out the value of rise time, settling time and percentage overshoot.
Thanks,
Rachana
