Can "Pause on Errors" be enabled by a script, or set as the default?
显示 更早的评论
I run many processes that take a day or more to run, and sometimes they encounter unexpected errors. I don't always think to turn on "Pause on Errors", but when an error ocurrs, I wish that I had. Is there a way to set this in my script, or configue MATLAB such that this is the default behavior?

dbstop if error
It is sometimes useful to use
dbstop if caught error
However, it turns out that caught errors are expected in routines such as ode45() and integrate() so it can get a bit frustrating to deal with all the caught errors sometimes.

If you only wanted to stop at a catch block in your own code (not MathWorks code), as long as you have a small number of them, you could use the dbstop in <file> at <location> command once per catch block (hence "small number of them") to stop on the first executable line inside the catch block.
Or if you always wanted to stop in the catch block, without worrying about the specific line number where the try / catch occurs, you could call a helper function that does nothing but has an executable line in it (1+1; for example) at the start of the catch block and set a breakpoint to stop in that helper function on that line (which is unlikely to change.) Or if you always want MATLAB to enter debug mode in that case, call keyboard as the sole line in that helper function (or just call keyboard in the catch block.)
function anchorForStopping % in anchorForStopping.m
1+1; % or keyboard;
end

Pausing on error is not compatible with MATLAB Coder.
