You need to be in debug mode. Put a break point on the line and then run the file. NOTE You can not debug sections so you will need to run the file with Run button or by calling the filename.

Hello Teeratorn Kadeethum
I have a similar problem. When I terminate a script with CTRL+C all Matlab Run commands are grayed out. This can be sorted out if you close your script and reopen it. It seems to be a Matlab bug to me... Tried F5, return, dbcont or dbquit but nothing seems to work. The fact that you have to close the script and reopen it makes me think that is something to do with Matlab not realising that the script has ended.

I am having the same issue. On my lab computer (at school), when I try to debug a function (run and stop at a breakpoint) all progression buttons are grayed, meaning I cannot step through or stop the debugging. All I can do is "Run to Cursor" which is very frustrating. This computer has MatlabR2015b and MatlabR2015a installed on it, and this issue exists in both.
On my personal computer Matlab runs perfectly. So whats going on? Are there permission issues? Please help!

I had the same issue. my script calls and runs some functions which I wrote in different matlab files. I just ran another script which was for the test and the problem solved. also, reopening it works.

I had the same issue. I think I solved it by repairing my pathdef, which was corrupted (there was a rogue newline in the p-array).

it happened to me too, it turns out that the keyboard function lock was turned on.
To disable it try pressing Fn+Esc and then try using the F buttons.
It solved the problem for me!
