Hi. I'm using the parfor in order to change some labels name:
Data = cell(1, length(DirList));
numberOfDbExamples = length(DirList);
parfor k = 1:numberOfDbExamples
Data{k} = load(fullfile(Folder, DirList(k).name));
[newLabelNames, newMask] = changeLabelNames(Data{k}.labelNames, Data{k}.mask);
Data{k}.labelNames = newLabelNames;
Data{k}.mask = newMask;
end
I get this error:
The source code (C:----) for the parfor-loop that is trying to execute on the worker could not be found.
Caused by:
Undefined function changeLabelNames for input arguments of type table.
Error using remoteParallelFunction
Do you have an idea of how fix it?

The function is stored as changeLabelNames.m and it is located in the same folder of the script.

@Mehdi I just noticed your https://www.mathworks.com/matlabcentral/answers/1897595-why-receive-error-integrand-output-size-does-not-match-the-input-size?s_tid=srchtitle in which you are expecting that your function might return a constant and so not automatically vectorized by matlabFunction . There are better ways of dealing with that situation.

I did something similar to what Walter mentioned, but I don't remember exactly.
