How to save Variable in workspace from real time simulation with timestamps

Hello I have a real time simulation in Simulink and i would like to save the date/variables in workspace with timestamps. i tried it with scope block. but it is just showing the current value.

please help.

Hi Siyaram,

I understand that you want to store the simulation output in the MATLAB workspace with timestamps.

To achieve this, you can employ the "To Workspace" block in Simulink, which allows you to write data directly to the MATLAB workspace. Configure the "To Workspace" block parameters like "Variable name" and "Save Format" as per your needs(by default it's set to "Timeseries").

Below is a self-explanatory script that demonstrates how you can run the model and extract the output data from the "To Workspace" block:

% Define the Simulink model name
modelName = 'your_model_name';

% Simulate the model
out = sim(modelName);

% Extract the output from the "To Workspace" block
% assuming the variable name is set to default "simout"
toWksData = out.simout;
% Extracting the time and data from the output
time = simout.Time;
data = simout.Data;

For more details, please refer to the following MathWorks documentations:

• To Workspace block - https://www.mathworks.com/help/simulink/slref/toworkspace.html
• Run Simulations programmatically - https://www.mathworks.com/help/simulink/ug/using-the-sim-command.html

Hope this helps!
