Hi, I want to extract the time of a out.simout into a variable called "t". The following code works for MATLAB version 2018a but does not work for MATLAB version 2022a (the version that I am using). Moreover, I had referred to a similar question asked but it does not solve my problem. In the command window it says "Unable to resolve the name 'simX.Time'."

The following are my MATLAB code and an image showing my Simulink model:

:

t = simX.Time;
u1 = simU.Data(:,1);
u2 = simU.Data(:,2);
u3 = simU.Data(:,3);
u4 = simU.Data(:,4);
u5 = simU.Data(:,5);
x1 = simX.Data(:,1);
x2 = simX.Data(:,2);
x3 = simX.Data(:,3);
x4 = simX.Data(:,4);
x5 = simX.Data(:,5);
x6 = simX.Data(:,6);
x7 = simX.Data(:,7);
x8 = simX.Data(:,8);
x9 = simX.Data(:,9);

As it indicates in the Simulink model, the data is saved in "out.simU". So, add "simX=out.simX;simU=out.simU;" in front of your code
Or, Press Ctrl+E at your Simulink model, select "Data Import/Export" on the left column, uncheck "Single simulation output" option.
