Find max value comparing multiple arrays for each index

Question

I\'m trying to find a method to find the max value comparing multiple(unknown number, but same length) arrays for each observation in the arrays, returning an array with the max

Answer 1

For each index of the array, create an array containing all elements in the "column" and find the max of those values. Return the generated array. Sample usage: maxValues(A) would give the desired result.

function maxValues(array) {
    var maxArray = [];
    var length = array[0].length;
    for (var i = 0; i < length; i++) {
        var ithColumn = [].map.call(array, function(array) {
            return array[i];
        });
        maxArray.push(Math.max.apply(null, ithColumn));
    }
    return maxArray;
}
