Given a system described as an LTI object, the lsim command can run a simulation of the system using arbitrary inputs and initial conditions. Plot looks okay, but for some reason Matlab inserts a backslash before underscore for the step legend. If there are no multiple roots, B(s) R(1) R Frequency Response in Matlab. The solution of the ODE (the values of the state at every time). I'm tryng to implement a control system method in matlab but I have a problem in plotting a curve so I don't find a solution to compute the absolute value of a tranfer function declared with the classical command "tf". However, the concept of tf–idf did not prove to be more effective in all cases than a plain tf scheme (without idf).

Matlab allows you to create symbolic math expressions. Also, MATLAB is a weakly typed language and it is not (for example) sure that f really is a function handle (since you say you have a problem). tf m matlab
