In addition to that, you can try several suggestions to reduce CPU memory usage, such as optimizing your code and clearing variables. It's also important to check for memory leaks and deallocate unnecessary memory using the clear command. Using memory-efficient data structures like sparse matrices or cell arrays instead of regular arrays can also help.
For more strategies to save memory, go through the following documentation:
Hope this helps,
