I'm both trying to implement an ODE45 version, and comparing it to 'step' or 'lsim'. Later, I want to incorperate a nonlinear system and prefer to use the ODE45, so that is why I am trying this. The result is not promising: Furthermore, if I increase the ...

% plot the step response. step(sys); This code defines a transfer function with a numerator of 1 and a denominator of [1, 2, 1]. The resulting transfer function object, "sys", can be used to analyze and simulate the system. The transfer function can also be used for system identifica...
