1. The problem statement, all variables and given/known data I need to find a system rise time (from 10% to 90%) using matlab. Is this code right? 3. The attempt at a solution Code (Text): sys = tf(num, den); y= step(sys, t); tr1 = max(ﬁnd(y<0.1)); tr2 = min(ﬁnd(y>0.9)); rise_time = t(tr2) - t(tr2); Is this seems to be right?
