Default values to the function arguments are not allowed in MATLAB, in case you are looking for a workaround, follow the MATLAB answers articles and documentation mentioned below:

• Set default value for custom function in MATLAB: How to set a default value for my custom function - MATLAB Answers - MATLAB Central
• Creating a function in MATLAB: How to Create a MATLAB Function - Video - MATLAB
• How to use MNIST in MATLAB: Using MNIST in MATLAB - MATLAB Answers - MATLAB Central

If you face any further issues with the MATLAB fundamentals, I would recommend you to take the MATLAB onramp course:
