To debug a parfor loop, first remove the par and try to run it as a normal loop.
It's possible something in your funcList is not capable of operating across three arrays at once.
If you are trying to apply each function to each array separately, you need 9 outputs for the code above. In that case, something like the following might work:
funcList = {@(x) sum(x,'all'), @(x) prod(x,'all'), @(x) std(x,[],'all')}
dataList = {magic(3),magic(4),magic(5)}
% Precalculate/preallocate things where it makes sense
nd = numel(funcList)*numel(dataList);
arrayidx = rem((1:nd)-1,numel(funcList))+1
funidx = floor(((1:nd)-1)./numel(funcList))+1
results = cell(numel(funcList),numel(dataList));
parfor idx = 1:nd
results{idx} = funcList{funidx(idx)}(dataList{arrayidx(idx)});
end
results
