How can I save PDSCH parameters from App-Based 5G waveform generation

I was working on the App-Based 5G waveform generation, debuging the PDSCH parameters. I want to storage these parameters in to a .mat file or whatever files. I have tried to "Save Seesion", but that .mat files doen't contian data like PDSCH coressponding. How can I resolve this?

Hi Lawson,

When working with MATLAB App Designer applications or similar environments, "Save Session" might not capture all the specific variables or data structures you want, such as PDSCH parameters. Instead, you can manually save the necessary parameters to a `.mat` file. Here's how you can do it:

Steps to Save Parameters to a `.mat` File

1. Identify the Parameters:

- Determine the specific variables or structures you want to save. For example, if you're working with PDSCH parameters, identify the relevant variables in your workspace or app.

2. Use the `save` Function:

- You can use the `save` function in MATLAB to store specific variables into a `.mat` file. Here’s a basic example:

% Assuming pdschParams is your variable containing the parameters
   pdschParams = struct('Modulation', 'QPSK', 'RNTI', 1, 'RV', 0); % Example structure

   % Save the variable to a .mat file
   save('PDSCHParameters.mat', 'pdschParams');

3. Saving from an App:

- If you are working within an App Designer app, you can include a callback function (e.g., a button press) to save the parameters:

% Inside your app function
   function saveParametersButtonPushed(app, event)
       % Collect PDSCH parameters from the app properties or UI components
       pdschParams = struct('Modulation', app.Modulation, 'RNTI', app.RNTI, 'RV', app.RV); % Example structure

       % Save to a .mat file
       save('PDSCHParameters.mat', 'pdschParams');
   end

4. Verify the Saved Data:

- After saving, you can load the `.mat` file to verify that it contains the expected data:

 % Load and check the saved parameters
   loadedData = load('PDSCHParameters.mat');
   disp(loadedData.pdschParams);

Refer to the following documentation to understand more:-

Additional Tips

- Organize Data: Consider organizing your parameters into structures for easier management and saving.

- File Management: Ensure you have write permissions in the directory where you are trying to save the file.

- Error Handling: Implement error handling in your code to manage situations where saving might fail due to permission issues or incorrect paths.

- Documentation: Comment your code to document which parameters are being saved and why, for easier maintenance and understanding.

By manually saving the parameters using the `save` function, you gain control over exactly what data is stored, ensuring that all necessary parameters are preserved for future use.

Thank you.
