When the function that splitapply throws an error, this line number of this error is not include in the output (matlab2024b)
Example:
T=table([1:3]’);
G=findgroups(T);
splitapply(@fun, T, G);
function out = fun(varargin)
ERROR
end
This returns:
Error using splitapply>localsplitandapply (line 196)
Unable to apply the function ‘fun’ to the 1st group of data.

Error in splitapply (line 135)
varargout = localsplitandapply(fun,dataVars,gdiffed,sgnums,gdim,nargout);

Error in templateLoopOverAll (line 231)
splitapply(@fun, T, G);

Caused by:
Unrecognized function or variable ‘ERROR’.

I was expeting that the line number that actually caused that error would be included:
Error in testfile>fun (line 5)
ERROR

Error in testfile (line 3)
fun()

Missing this information makes the debugging of fun very challenging.
