编辑： usa usah 2016-2-16

When I am working on a project, I keep on making some changes in my m-file, so there comes a star(*) near the name of the m.file (which means its not saved). But I make some changes and run the m-file, its gets saved automatically, so I lose the things which I just edited.When I am editing many things I don't remember what all I changed. I know I can use the % symbol to prevent something from getting complied. I think this the new feature of Matlab 2015a. But this was not happening before in 2014a version. I want Matlab to always ask me before it saves anything. Is this possible. If yes, pls tell me the setting how 2 do this? Thanks.

在 MATLAB Online 中打开

One possibility is to use code sections. Surround sections of code with "%%" like this

% This code is in one cell
x = 5
% This code is in the next cell
x = 6
% This code is in the next cell
x = 7

Then, in the editor,click anywhere in that section, then right-click and select "Evaluate this section". (There is also a keyboard shortcut.) It will evaluate your edited code, but not save it.

You can surround all of your code with %% ... %%, and run the whole code that way.

The autosave behavior was new in R2014b. You can disable it in preferences

As for making lots of changes, the use of sections like the Cyclist has proposed is good. You also might consider using GIT or SVN to keep track of changes that you commit etc.
