Runs MATLAB script and gives output

## Install

```

$ npm install node-matlab

```

## Requirements

MATLAB 2019a or later must be installed on your pc, you don't need to install Python/Jupyter Notebook or MATLAB kernel

## Usage

```js

// One Line

const matlab = require("node-matlab");

matlab

  .run("3+4")

  .then((result) => console.log(result))

  .catch((error) => console.log(error));

// 7

```

You need to escape "\n", "\r" etc. to run multiline scripts

```js

// Multi Line

const matlab = require("node-matlab");

matlab

  .run(

    `clc;

clear;

counter = 0;

period = 0.1;

totalTime = 2;

for number = 0:period:totalTime

  counter = counter + 1;

  array(counter) = -2 * cos(2 * pi * 2 * number + deg2rad(47));

  fprintf("t(%g) = %g\\n", number, array(counter));

end

  `

  )

  .then((result) => console.log(result))

  .catch((error) => console.log(error));
