I understand that you want to efficiently store and transfer dense matrices in your programs.
Here are some suggestions which might help you:
- To avoid repeated transfers, you can make the matrix a “global” variable; however, this must be used sparingly and specific to the application. Refer to the documentation of “global” : https://www.mathworks.com/help/matlab/ref/global.html
- You can also use “persistent” storage to preserve a variable inside a function between repeated function calls. To use “persistent” efficiently, refer to the documentation of “persistent”: https://www.mathworks.com/help/matlab/ref/persistent.html
- To store matrix efficiently, you must ensure the correct datatype to use which can save space since storing a double is costlier compared to “int32” data type, if entries are single precision, then use “int32” or “single” instead of “double”.
- You must use optimized function like “A*a” for efficient matrix vector multiplication to boost up speed as the internal implementations are highly optimized for performance.
You can try implementing the above suggestions to the problem.
I hope this will help!
