What happened to errors

I use MATLAB in my 3rd year course. I use live scripts (mlx), as they are best for teaching. In v2024, the following code would output a clear error "Not enough input arguments." But, in v2025, I just get no error information. How do I turn error explanations back on?

%% A simple bugged code usage
function seq=RUNME(a,b)
seq(1)=a;
for i=2:b
    seq(i)=seq(i-1)/b;
end
end
RUNME(1)

Starting from R2025a, (local) functions can be defined anywhere in a script. They don't necessarily have to be at the end of the script code anymore.

"How do I turn error explanations back on?"

You will have to revert to an older version of MATLAB.

Well that's disappointing. Perhaps the next release will reinstate the feature, as it was extremely useful in the classroom.

Fixes from IT arrived (and worked). In case anyone else has this problem...

• Go to Home → Environment → Settings
• Navigate to MATLAB → Editor/Debugger → Display
• Ensure Live Editor Default view is set to Output on the right.
• Make sure the view space is sufficiently wide to view outputs.
