while debugging, one core constantly running
显示 更早的评论
got a new laptop, installed 18a. If I'm debugging, one of my cpu cores is constantly railing (i.e. task manager says matlab is using ~25% cpu) and it decreases battery life.
Also, sometimes matlab freezes, when I'm not looking at it, and I have to restart

Do you use Win or Linux version of MATLAB?

It appears you have encountered this issue: Bug report 1736753 I suggest contacting support for possible workarounds and solutions. You may find that closing extra figure or MATLAB desktop windows makes the problem go away the next time you debug. Using breakpoints instead of dbstep may also help.

I've the same problem on Linux (MATLAB 2018a). The load of one core is about 80-90% at using breakpoint.

The bug was fixed in 2018b. I tested on my Linux PC.
