LaTeX-α² (`latexalpha2`) is a LaTeX package that can execute Wolfram Language codes and show the corresponding results inside LaTeX documents.

The package is heavily inspired by [LaTeX-Alpha](https://github.com/Akollek/LaTeX-Alpha). Unfortunately, LaTeX-Alpha has been down for a while. The aim of this package is to replace LaTeX-Alpha, as well as to provide various new features.

The codes can be executed either locally (via locally installed Mathematica) or on the cloud (via [Wolfram Cloud](https://www.wolframcloud.com/)) using the [WolframScript](https://www.wolfram.com/wolframscript/) interpreter. In addition, you can also use [Mathics](http://mathics.github.io) (a free, open-source alternative to Mathematica) for computations.

The package only supports Unix-like system for now. Pull requests are welcome.

### Usage

- First install [WolframScript](https://www.wolfram.com/wolframscript/) (or [Mathics](http://mathics.github.io)) if you haven't already done so. You can use `type wolframscript` or `type mathics` to check if it's properly installed.

- Download `latexalpha2.sty` to the same folder as your `.tex` file:

```

curl -O https://raw.githubusercontent.com/stevenliuyi/latex-alpha2/master/latexalpha2.sty

```

To avoid copying the file every time, please see the [installation guide](#installation) below.

- Add `\usepackage{latexalpha2}` to the preamble of your document. All the codes will be run locally by default. If you'd like to run on the cloud, use `\usepackage[cloud]{latexalpha2}` instead. For the Mathics mode, use `\usepackage[mathics]{latexalpha2}`.

- LaTeX must be invoked with the `-shell-escape` flag in order to run WolframScript (or Mathics). For example: ```pdflatex -shell-escape example.tex```.

Please refer to the [documentation](https://raw.githubusercontent.com/stevenliuyi/latex-alpha2/master/latexalpha2.pdf) for more information.

### Examples

#### `\wolfram{}`

Input:

```tex

$\wolfram{Series[Exp[x],{x,0,5}]}$

```

Output:

![](http://latex.codecogs.com/gif.latex?1+x+\frac{x^2}{2}+\frac{x^3}{6}+\frac{x^4}{24}+\frac{x^5}{120}+O(x^6))

#### `\wolframgraphics{}`

Input:

```tex

\begin{figure} 

    \wolframgraphics[pdf]{Plot3D[Sin[x]Cos[y], {x, -2Pi, 2Pi}, {y, -2Pi, 2Pi}]}{example}

    \includegraphics{example.pdf}

    \caption{Plot of $f(x,y)=\sin(x)\cos(y)$}

    \centering

\end{figure}

```

Output:

![Example Plot](images/example.png?raw=true)

Input:

```tex

\begin{figure} 

    \wolframgraphics[pdf]{GeoGraphics[{Red,Thick,GeoPath["DateLine"]},GeoRange->{All, {90, 270}},GeoGridLines->Quantity[15, "AngularDegrees"]]}{example2}

    \includegraphics{example2.pdf}

    \caption{International Date Line}

    \centering

\end{figure}

```

Output:

![Example Plot 2](images/example2.png?raw=true)

#### `\wolframalpha{}`

Input:

```tex

The population of Shanghai is $\wolframalpha{population of Shanghai}$, which is $\wolframalpha{ratio of Shanghai populatioin and NYC population}$ times the population of New York City.

```

Output:

The population of Shanghai is 2.415×10⁷ people, which is 2.814 times the population of New York City.

Input:

```tex

$\wolframalpha{Compton scattering for electron}$

```

Output:

![](http://latex.codecogs.com/gif.latex?\Delta\lambda=(1-\cos(\theta))\left(0.0019569512\text{h}\\,\text{c}/\text{keV}\right))

#### `\wolframdsolve{}`

Input:

```tex

\wolframdsolve{y'[x]+y[x]==a*Sin[x]}{y[x]}{x}

```

Output:

![](http://latex.codecogs.com/gif.latex?y(x)=\frac{1}{2}a(\sin(x)-\cos(x))+c_1e^{-x})

#### `\wolframtable{}`

Input:

```tex

\begin{tabular}{ccc}

    \hline

    \wolframtable{Join[{{x,x^2,x^3}}, Table[{i,i^2,i^3},{i,5}]]}

    \hline

\end{tabular}

```

Output:

![Example Plot 3](images/example3.png?raw=true)

### Installation

To avoid copying the `latexalpha2.sty` file for every new project, you could install the package instead. Just put the `.sty` file in the `texmf/tex/latex` folder (for TeX Live, it would be `/usr/local/texlive/texmf-local/tex/latex` by default), and then run `sudo texhash` to update the package database.
