Usage

import { ObjectMatrix } from "object-matrix-js";

const obj = new ObjectMatrix({ width: 10, height: 10 });
obj.init();

for (let i = 0; i < 10; i++) {
  for (let j = 0; j < 10; j++) {
    obj.setValue(i, j, obj.width * j + i);
  }
}

obj.width
// 10

obj.height
// 10

obj.data
// [
//    0,  1,  2,  3,  4,  5,  6,  7,  8,  9, 10, 11,
//   12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23,

obj.getIndex(1, 2);
// 21

obj.getValue(1, 2);
// 21

obj.getRow(0)
// [ 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 ]
