Mad Matrixes

A dead simple javascript library built for quick editing of matrixes (or matrices). Made for those who can't be bothered to type out the whole thing.

Installation

Get it from npm ➡️ npm install --save mad-matrixes.

Examples

const {Matrix, parseMatrix} = require("mad-matrixes");

Create a new Matrix of size 3x3 where each point has a value of "something":

let m = new Matrix(3, 3, "something")
let myMatrix = m.getArray();
/*
let myMatrix = [
    [["something"],["something"],["something"]],
    [["something"],["something"],["something"]],
    [["something"],["something"],["something"]]
];
*/

Make a line vertically down a column in a matrix:

let myOtherMatrix = m.addVerticalLine(1, 0, 2, "something else").getArray();
/*
let myOtherMatrix = [
    [["something"],["something else"],["something"]],
    [["something"],["something else"],["something"]],
    [["something"],["something else"],["something"]]
];
*/

(Note the .addVerticalLine and .addHorizontalLine methods can be chained!)

let anotherMatrix = m.addVerticalLine(1, 0, 2, "something else").addHorizontalLine(1, 0, 2, "something else").getArray();
/*
let myOtherMatrix = [
    [["something"],["something else"],["something"]],
    [["something else"],["something else"],["something else"]],
    [["something"],["something else"],["something"]]
];
*/

Got one of your own that you want to use? Don't like the normal constructor? Want to just be different? Use the parser!

const {parseMatrix} = require("mad-matrixes");

let mySpecialMatrix = [
    [["something"],["something"],["something"]],
    [["something"],["something"],["something"]],
    [["something"],["something"],["something"]]
];

// Returns a Matrix object, which you can use all the standard features on.
parseMatrix(mySpecialMatrix);

// Or, if you already required the Matrix class, you can pass the array as the first argument :)

let mySpecialMatrix = [
    [["something"],["something"],["something"]],
    [["something"],["something"],["something"]],
    [["something"],["something"],["something"]]
];

new Matrix(mySpecialMatrix)

FAQ

What is a Matrix?

Unfortunatelty, we're not talking about the movie. 😔 A matrix is a 2D grid represented by JavaScript arrays. They can become quite big though, and this library aims to remove dealing with super long arrays.

How do I get it as an array?

If you're wanting to use your Matrix somewhere, you'll probably be wanting to know this. You can call the .getArray() method on any Matrix object to get it as a fancy array!

How do I format it properly?

If you need to be able to see your array properly, you can use the .getString() method to get your matrix as a more readable string!
