How to output a tout from Simulink space to Matlab so that it reads the value to us?

54 views (last 30 days)
During the simulink simulation, I have a problem with the derived "tout" in m-matlab file gives me an error "Unrecognized function or variable 'tout'." but tout is in the workspace in ANS, I wanted to draw the graphs in matlab and I derived "OUT" from the simulink, and "tout" from the simulation. Please help me and best regards.
sim('cw_6_silnik') % simulink file name
Unable to find system or file 'cw_6_silnik'.
t=tout;
delta=yout(:,1);
n=yout(:,2);
T_e=yout(:,3);
T_a=yout(:,4);
P_e=pi/30*T_e.*n;
figure(1)
plot(t,delta,'b'), grid on
xlabel('t [s]')
ylabel ('\delta [deg]')

Hi @Krzysztof, when I want to access variables from simulink, plot them etc.
I use to Workspace block in simulink and choose Array option, just like shown in the image below.
% Check if out variable is accessible in Workspace
whos out
% Plot
plot(out.time, out.output);
hold on:
plot(out.time, out.input);
hold off;

sim('cw_6_silnik')
whos out
plot(out.time, out.simout);
hold on:
plot(out.time, out.simout1);
hold off;
data from out "to workspace" appears but I can't process it further

No problem. So it seems this is changed in newer Simulink versions. In old version (2021a at least) the output variable was
'Simulink.SimulationOutput'
