多维数组javascript的最大值
问题描述：
我有一个x列和y行的多维数组。
如何找到矩阵的最小值和最大值？
示例
I have a multidimensional array of x columns and y rows. How to find the min and the max value of the matrix? Example
[1, 37.8, 80.8, 41.8],
[2, 30.9, 69.5, 32.4],
[3, 25.4, 57, 25.7],
[4, 11.7, 18.8, 10.5],
[5, 11.9, 17.6, 10.4],
[6, 8.8, 13.6, 7.7],
[7, 7.6, 12.3, 9.6],
[8, 12.3, 29.2, 10.6],
[9, 16.9, 42.9, 14.8],
[10, 12.8, 30.9, 11.6],
[11, 5.3, 7.9, 4.7],
[12, 6.6, 8.4, 5.2],
[13, 4.8, 6.3, 3.6],
[14, 4.2, 6.2, 3.4]
答
让
var arr = [[2,3], [4,5]]; //a multidimensional array
然后得到一个数组，其中每行的最大值为
then get an array with each row's maximum with
var maxRow = arr.map(function(row){ return Math.max.apply(Math, row); });
以及
var max = Math.max.apply(null, maxRow);
