var a = new Matrix([
[1, 3, 7],
[3, 4, -3],
[3.5, 2, 22]
]);
var b = new Matrix([
"1 3 7",
"3 4 -3",
"3.5 2 22"
]);
// add together:
var c = Matrix.add(a, b);
// or:
var c = a.add(b);
// multiply together
var d = Matrix.multiply(a, b);
// or:
var d = a.multBy(b);
console.log(d.toString()); // will format it nicely
