Hi, I know we suppress assignment statements in script so we can format the output and also some of the info is unnecessary to the user. However, I was wondering does supressing statements always save memory space?
Thanks

For what it's worth, for me the question is a bit strange as I see the default state of code as not outputting to the command prompt and therefore, you enable (don't suppress) output if needed. It's only semantics but reflects a different coding outlook.

It can save memory. Every "page" (2D array) that is displayed is formatted consistently when you use format short (the default), and the only way that can happen is if it takes a copy of the slice to find the maximum and minimum absolute values -- a process that takes temporary memory. With sufficiently large arrays, that could add up substantially.
... Of course, with arrays that large, displaying them would be quite time consuming.
