function maxArrivalDelayReducer(intermKey, intermValIter, outKVStore) % Reducer function for the MaxMapreduceExample. % Copyright 2014 The MathWorks, Inc. % intermKey is 'PartialMaxArrivalDelay'. intermValIter is an iterator of % all values that has the key 'PartialMaxArrivalDelay'. maxVal = -inf; while hasnext(intermValIter) maxVal = max(getnext(intermValIter), maxVal); end % The key-value pair added to outKVStore will become the output of mapreduce add(outKVStore,'MaxArrivalDelay',maxVal);
