Hello,
I have been using my current version of Matlab for months, (R2011a), and I was using it no less than 20 minutes ago, and now it won't run. I push the run button, and nothing happens or changes. It was working, then all of a sudden it stopped for no reason.
Thank you, Heather

I have tried restarting MATLAB, restarting computer. I don't get any kind of error because it doesn't even attempt to run my code. I can write all the code I want, I just can't seem to get it to run. I just tried publishing the code, and it still doesn't work. I also just noticed there aren't any ">>" in my Command Window to work with either.

Check if it's running an infinite loop. and press control c to stop that.
That's what was happening to me when i couldn't run my code

Close your Matlab session, then reopen it

I got the very same problem. The code was running like a charm a minute ago, and then nothing... and when you run and go to the next part of the code, it does so, but it does not spill any result anymore... just weird... (Version 2017)

Try to change the name of script.m file. This happens if you have 2 files with the same name.

I had the same problem. To fix it I closed Matlab and restarted it.
But a temporary workaround is just to save the .m file and then run it by typing the name in the command window.

I was having same problem, i clicked 'clear data' multiple times then it started showing something on command window,,,so i clicked 'ctrl+c' to stop all executions. it worked.

For certain older versions of MATLAB, and more common on Mac, MATLAB could apparently hang at random times, including on start-up. The problem had to do with Source Control. The workaround was
Preferences -> Source Control -> MATLAB Source Control Preferences -> Source Control Integrations -> [ ] Enable source control
which you would need to uncheck.
The hanging problem was supposedly fixed several releases ago -- but not long ago I did see a post from someone indicating the turning off source control fixed problems for them on a relatively recent release.
