打印给定矩阵中每行的最大值

function printMaxValues(matrix) {
  var max_values = [];

  for (var i = 0; i < matrix.length; i++) {
    var max_value = matrix[i][0];

    for (var j = 1; j < matrix[i].length; j++) {
      if (matrix[i][j] > max_value) {
        max_value = matrix[i][j];
      }
    }

    max_values.push(max_value);
  }

  console.log(max_values);
}

// 示例矩阵
var matrix = [
  [1, 2, 3],
  [4, 5, 6],
  [7, 8, 9]
];

printMaxValues(matrix);
