水平二维矩阵变换（比例）-JAVASCRIPT

我有一个2d矩阵，如下例所示：

00000000000000000000000000000000000000000000000000
00110000011000111111000110000000110000001111100000
00110000011000110000000110000000110000010000010000
00110000011000110000000110000000110000010000010000
00111111111000111111000110000000110000010000010000
00110000011000110000000110000000110000010000010000
00110000011000110000000110000000110000010000010000
00110000011000111111000111111000111111001111100000
00000000000000000000000000000000000000000000000000

我想通过用一个特定的因子水平缩放矩阵来变换这个矩阵（例如2.0或0.5，…），这样矩阵之后看起来像这样：

000000000000000000000000000000000000000000000000000000000000000000000000000000 ...
00111100000000000111100000011111111111111000000111100000000000000 ...
00111100000000000111100000011110000000000000000111100000000000000 ...

var matrix = [
  '001000100001',
  '001111101100',

Array.prototype.scale_水平=函数（系数）{
var矩阵=此；
var new_matrix=new_matrix（matrix.length，矩阵[0]。长度*因子，0）
对于（var y=0；y您可以将其全部放在一个函数中：

function scaleHorizontal(matrix, factor) {
    var scaledMatrix = [];
    for(var i = 0; i < matrix.length; i++) {
        var row = '';
        for(var j = 0; j <= matrix[i].length - 1; j += (1 / factor)) {
            row += matrix[i][Math.round(j)];
        }
        scaledMatrix.push(row);
    }
    return scaledMatrix;
}

逻辑是“总是从两个00开始，然后将相同的数字块乘以因子”？非整数如何？错误？向上取整？向下取整？您总是从第一个2d矩阵开始，还是多个变换应该能够相互作用？
