Simulink considers that an output matrix has variable size when the size is always constant
You have "Ga=zeros(nr,ns)" so the size of Ga is fixed in your mind. But it is not the case for Simulink. Since nr and ns all com...

Checking the value at a specific point in time with display in Simulink
u<=133, not u=<133. A better way is below. Make sure to set the solver so the simulation can hit the time point.

Hi, i want to plot two columns of values of data from excel, the graph includes a zero while the excel sheet doesn't. Here is my code and the graph I got vs what I should get
I think the last data point (un-wanted) is at (0,0). Your data shows it. You can look at the value of q and D_q.
