I want to use a parfor loop. My goal is to cut a tall column array in pieces to evaluate a smaller data amount. So far matlab underlines my variable dataBin with the message it's a broadcast variable

% dataBin = tall column array
% chunkLen = length of a chunk, to get a small part of the tall column array for evaluation using gather
parfor c = 1:numbCh
    temp = dataBin((c-1)*chunkLen + 1 : c*chunkLen);
    
    % ...some calculations returning vector..
    dataCell(c,1) = vector;    
end
