Is there a way to 'fold up' sections of code - like when you close up a for loop

Is there a way to hide sections of code - like when you close up a for loop?
I have quite a long code with a few different sections, and while I'm working on one section I'd like to hide the other sections so the code is a bit more manageable to get around.

Inserting artificial code loops inserts extraneous code and reduces readability if the code is published. The drawback of the existing %% code section approach is there is no end-section marker. It means you can't create an isolated code section in the same way as code blocks like a for loop. I'd love to seem Mathworks introduce a system of %%<section_start> and %%<section_end> tags.

@Kevlin Prosyk, I agree wholeheartedly. I try to use "%%" to held organize collapsible sections, but the auto-end-section significantly limits the ability to manage sections due to erratic updates and inconsistent operation. Frankly, one of the earliest languages I ever used, Pascal maybe, used "//" to comment the remainder of the line, and "/* ... */" to comment sections. I've been annoyed by any language since that did not allow the programmer to comment sections. And with the added benefit of modern code-folding,... controlling exactly how you'd like to fold you sections would add wonderfully for those of us love of clean, organized code.

Under preferences you can enable code folding for blocks. Blocks are defined in MATLAB as sections starting with %% (I am not sure if they can have anything else on the line).
So you should be able to fold
a=1;
b=2;
x=3;
y=4;

Try this:
for d = 1
[Your code here]
end
its collapsable on demand and doesn't effect the code at all (someone please correct me if I'm wrong). It can be used as many times as you like for each section of the code.

I recently discovered this trick has its shortcomings. You can't define functions instead of control statements (even if it is just a loop that doesn't actually loop).
I wish that you could define the end of code sections so you could nest code sections inside of code sections.

I think you mean "inside of control statements" rather than "instead of control statements" ?
