About LaTeX

We follow the LaTex in our lab, so we have LaTeX is a high-quality typesetting system; it includes features designed for the production of technical and scientific documentation. LaTeX is the de facto standard for the communication and publication of scientific documents. It is available as free software and is used for a wide range of documents, from simple letters to complete books. LaTeX uses TeX as its formatting engine. This system is particularly powerful for complex documents that include references and footnotes. There are many software to write in LaTex, but we follow overleaf. The detailed procedure to login and use overleaf is explained below:

Overleaf Sign-In and Initial Setup Guide

1. Navigating to Overleaf

• Open your web browser and go to Overleaf. Overleaf is a cloud-based LaTeX editor that supports real-time collaboration.

2. Creating an Account or Signing In

• New Users: Click on Register to create a new account. Provide an email address, create a password, and complete the registration.
• Existing Users: Click on Login and enter your email and password.

3. Overview of Overleaf Interface

• The dashboard allows access to existing projects, creation of new ones, and finding templates for various documents.

Creating and Managing Projects

1. Creating a New Project:

   • On your dashboard, click on "New Project" to start a new LaTeX document. You can choose to start from a blank project, upload an existing project, or select from a variety of templates.
   • Give your project a meaningful name that reflects its content or purpose.

   • Working on the Project:

   • The Overleaf editor is split into three main sections: the source code editor, the PDF preview, and the file tree/settings. You can write your LaTeX code in the source editor, and the PDF preview will update in real-time.

   • Use the file tree to organize your document's components, such as chapters, images, and bibliography files.

   • Compiling Your Document:

   • Use the "Recompile" button to compile your LaTeX code into a PDF document. Overleaf automatically detects errors and warnings displayed above the PDF preview.

Sharing Overleaf Projects

1. Collaborating on a Project:

   • Open the project you wish to share, and click on the "Share" button located at the top right of the page.
   • You can invite collaborators by entering their email addresses and selecting their permission level (can edit or can view).
   • Collaborators will receive an invitation to join the project. Once they accept, you can work on the document simultaneously.

   • Link Sharing:

   • For easier access, you can also share a project using a link. Choose the link-sharing option under the "Share" menu and select the appropriate access level. Copy and share the link with your peers.

Referencing

• Labeling and Referencing: Use \label{} to mark an element and \ref{} to reference it. latex \label{sec:mySection} % Labeling a section See Section~\ref{sec:mySection} for details.

This cheat sheet covers the basics to get started with LaTeX. For more detailed information and advanced features, consider referring to comprehensive LaTeX guides or the Overleaf Documentation.

Here's a Markdown-friendly LaTeX cheat sheet focusing on mathematical commands, covering the essentials like addition, square roots, powers, subscripts, fractions, and more. This guide is designed to be both comprehensive and easy to reference.

LaTeX Mathematical Commands Cheat Sheet

Basic Operations

• Addition/Subtraction: a + b, a - b
• Multiplication (Dot): a \cdot b
• Division (Fraction): \frac{a}{b}
• Square Root: \sqrt{x}
• Nth Root: \sqrt[n]{x}

Powers and Indices

• Power (Superscript): a^{b}
• Subscript: a_{b}

Fractions

• Simple Fraction: \frac{a}{b}

Text in Equations

• Text Within Equations: \text{your text here}

Integration

• Definite Integral: \int_{a}^{b} f(x) \, dx
• Indefinite Integral: \int f(x) \, dx

Summation

This cheat sheet covers fundamental mathematical commands used in LaTeX for various types of expressions and operations. It's a handy reference for quickly recalling how to format mathematical content within your LaTeX documents.

We use LaTex OCR for equation automation.

To run the model you need Python 3.7+

If you don't have PyTorch installed. Follow their instructions here.

Install the package pix2tex:

pip install "pix2tex[gui]"

Model checkpoints will be downloaded automatically.

There are three ways to get a prediction from an image.

1. You can use the command line tool by calling pix2tex. Here you can parse already existing images from the disk and images in your clipboard.

2. Thanks to @katie-lim, you can use a nice user interface as a quick way to get the model prediction. Just call the GUI with latexocr. From here, you can take a screenshot, and the predicted latex code is rendered using MathJax and copied to your clipboard.
