I am trying to learn MATLAB and i came across a command lsim and i opened its help and from there i get code and tried to simulate that code in my MATLAB . I get two plots in final output figure but i am confused why it gives two plots in final output figure despite the fact that each subplot contains two waveforms??what is the difference between these two subplots as shown in attachment?? What is above plot showing and what is its meaning?? and what bottom plot showing and its meaning??
The system being modeled Simulate Response to Square Wave is a 1-input, 2=output (SIMO) system, presenting the same input to both systems. The upper plot shows the output of the first system, and the lower plot shows the output of the second system. (They are clearly labeled.)
