Requiring/Loading

If you're using Composer to manage dependencies, you can include the following in your composer.json file:

{
    "require": {
        "royopa/mat-lab-php": "dev-master"
    }
}

or

composer require royopa/mat-lab-php

Then, after running composer update or php composer.phar update, you can load the class using Composer's autoloading:

require 'vendor/autoload.php';

Otherwise, you can simply require the file directly:

require_once 'path/to/MatLabPHP/src/MatLabPHP.php';

And in either case, I'd suggest using an alias.

use MatLabPHP\MatLabPHP as M;

Methods
