I want to simulate a simulation via Matlab code(in .m file) in Simulink.

sim('Mysim');
plot(f(:,1),f(:,2))
hold on
plot(simlog.poppet.flow_rate,'units','lpm');

Unfortunately it gives me error. But it can plot the figure if I write this comment into the Command Window. I feel terrible because of this stupid error.

If you have any idea, please don't hesitate.

Sincerely,

Emre

Hi Emre,

Where exactly did you put this 4 lines of code? I guess it is a separate script that calls the model and the the plotting. If it works in the command window, it should work from a script.

Please attach the model and the script so to have a look and see if I find out the issue.

Best,

Jesús
