Hello Fabian,
To enhance your progress bar in a MATLAB App Designer application while using parsim for running parallel simulations, you can utilize listeners to track the simulation progress. The main idea is to attach a listener to the SimulationOutput object generated by parsim, and use this to refresh your GUI's progress bar.Steps to Implement a Progress Bar with parsim:
- Prepare Your Simulink Model:First, make sure your Simulink model is set up to provide progress updates. This could involve adding a custom block or using a MATLAB Function block to send updates to the MATLAB workspace or trigger an event listener.
- Create a Listener for parsim:When you execute parsim, the SimulationOutput object it returns can have listeners attached to it. These listeners will be responsible for updating your progress bar.
- Refresh the GUI:The listener should execute a function (such as updategui.m) to update your progress bar in the app.
% Inside your App Designer app, set up the parsim and listener
function runSimulations(app)
% Configure your Simulink model for parallel simulation
in = Simulink.SimulationInput('your_model_name');
% Adjust the input if necessary (e.g., set parameters)
% Set up the listener for progress updates
listener = @(src, event) updateProgress(app, event);
% Run parsim with the listener
parsimOptions = 'ShowProgress', 'on', 'TransferBaseWorkspaceVariables', 'on';
simOut = parsim(in, ...
'ShowProgress', 'on', ...
'TransferBaseWorkspaceVariables', 'on', ...
'SetupFcn', @(x) addlistener(x, 'SimulationOutput', 'PostSimFcn', listener));
end
% Function to update progress in the GUI
function updateProgress(app, event)
% Extract progress information from event
progress = event.Progress;
% Update your progress bar in the app
app.ProgressBar.Value = progress; % Assuming you have a ProgressBar component
end
