Matlab command window doesn't work
773 views (last 30 days)
Hi, my Matlab Command window doesn't work. The two arrows right next to the fx are missing. If I type in something trivial like "a=3" nothing happens. I jump in to the next row but nothing happens. Please help me!
Here is a picture of what i mean.

Hi. It sometimes simply happens to me when I forget to end a if/for/while statement. In this case I was unable to solve the problem by restarting the program. All I had to do was type "end" or type a closing bracket, even after reopening the program. :)

Show the lower-right corner of the Command Window. Does it say something like "Initializing" or "Busy" there?
If it shows "Initializing", how long has it been initializing? How long since you started MATLAB?
If it shows "Busy", MATLAB is running some code. Depending on what that code is doing, it may take a while and you won't be able to execute other commands while that code is running. You can type ahead but they won't get executed until MATLAB has finished its current work.

Exactly the same happened with me...n i typed an end and its resolved ...it works.

You aren't really giving us much info here besides the core problem. Has it been working, and suddenly stopped? Or is this the first time you've used MATLAB?
Have you tried the obvious things like restarting MATLAB? Restarting your computer?
Have you changed anything significant on your computer before/after this problem?
This seems like a problem we might struggle to diagnose with you. You might want to contact Mathwork support.

I had the same problem, but restarting the program worked for me. What was absent for me before when it wasn't working (and appears to be absent in yours) is the two right facing carrots on the command line. I've just started using the program but if someone with more experience could pinpoint why those might disappear, that would most likely fix the problem.

Sorry, I don't have an answer. I just want to report that I have been having the same problem lately with Matlab R2017b, running on Windows 7. I am not new to Matlab or R2017b, but the problem seems to be happening daily for the past few days. The problem is intermittent.
When the problem arises, I don't have that command prompt, and yet Matlab is not "dead". For example, I can still click on the tabs in the Editor window and view the code from the open functions. I can even edit and save those functions. I can undock and dock the Command Window (but the >> prompt is missing either way). I can type in the command window, but it dot respond.
The problem shows up when running my code. I can force Matlab to close. When I restart Matlab, I can run the same code without problem, so I don't suspect coding problems such as endless loops. Even if that was a problem, I would think the Pausing button would give back control, but it does not.
One clue: When I click the X to close Matlab, I get a message "An operation is in progress". I give it a chance to try to stop the operation, but that does not work. Then I click End Now. I just did this, re-started Matlab, and ran the same code that "got stuck". It ran normally again, completing in about 10 seconds.

I am having the same problem, but...
Rebooting the laptop does not fix the problem. Nor does just restarting MATLAB.
Installing a newer MATLAB does not fix the problem! It suddenly started happening on 2020b, so I installed 2021b but that didn't resolve it.
Typing end or CTRL-C does not fix the problem.
I recently was having issues with MS Office, so I updated to O365. Is there some dependence on Excel???
