After you read this
tell us what you did exactly to save all the variables in the "main function". Explain what "not working" means. That is so vague as to be essentially worthless. Did you get an error message? Could you call load() but none of the variables were there?
Also explain what "share the full code" means. Are you using GUIDE or App Designer? Are you trying to share your program files with someone else so they can run your program themselves? Does your program create variables and you just want to give them the created variables in a .mat file but you don't want to give them the complete program to create the variables themselves?
