Can you help me why I got this notice when I run my matlab code on my friend's laptop while I didn't get that notice when i run that in my laptop?

Look in Preferences -> MATLAB -> Workspace and scroll to the bottom to control the array size limits.

Note: your friend might not have enough memory to run your program.
