MATLAB not responding when using NCORR

I am trying to do DIC analysis using the open source software NCORR. I am having issues with NCORR running as everytime I try to input analysis parameters or displacement parameters, MATLAB stops responding. I am wondering if i am running out of RAM space or if I need to clear cache or something.

Here's how you can troubleshoot and potentially resolve the issue:

1. Check RAM Usage

• Monitor RAM: While running NCORR, monitor your system's RAM usage. If you're nearing full capacity, MATLAB could become unresponsive.
• Increase Available RAM: If possible, increase the amount of RAM in your system. DIC analysis can be memory-intensive, especially with large images or datasets.
• Optimize Memory Usage: Close unnecessary applications and processes to free up RAM.

2. Clear Cache and MATLAB Workspace

• Clear Workspace: Use clear or clear all commands in MATLAB to free up workspace memory.
• Clear Java Heap Space: Sometimes, MATLAB's Java-based GUI can consume a lot of memory. Clear it using java.lang.Runtime.getRuntime.gc().

3. Update Software

• Update MATLAB: Ensure you're using the latest version of MATLAB compatible with NCORR.
• Update NCORR: Make sure you have the latest version of NCORR, as updates often fix known bugs and compatibility issues.

4. Check Image Size and Parameters

• Resize Images: Large image files can consume a lot of memory. Consider resizing them if possible.
• Adjust Parameters: Experiment with reducing the analysis resolution or parameters in NCORR to decrease memory usage.

5. Software Compatibility

• Compatibility Check: Ensure that your version of MATLAB is compatible with your NCORR version. Sometimes newer MATLAB versions might introduce changes that affect the functionality of add-ons.

6. Debugging

• MATLAB Diagnostic Tools: Use MATLAB's built-in diagnostic tools to identify potential issues.
• Check for Errors: Look at MATLAB's command window for error messages or warnings that might give clues about the issue.

7. Other Considerations

• Run as Administrator: Try running MATLAB as an administrator to ensure it has all necessary permissions.
• Check Disk Space: Ensure there's enough disk space, especially for MATLAB's temporary files and paging file.

8. Community and Support

• NCORR Forums or Community: If the problem persists, reach out to the NCORR community or forums. Others may have experienced similar issues and might have solutions.
• MathWorks Support: Consider contacting MathWorks support for assistance, especially if the issue seems related to MATLAB itself.

9. Alternative DIC Software

• If NCORR continues to be problematic, consider exploring other DIC software that might be more compatible with your setup.
