Find LaTeX commands by document task

Filter by equation command, table syntax, figure workflow, reference tool, or technical writing use case.

LaTeX

Best for

Technical reports

Use the table to write clean equations, references, tables, figures, and units in engineering documents.

Watch out

Packages add commands

Many useful commands require packages such as amsmath, graphicx, booktabs, siunitx, or hyperref.

How to use

How to use LaTeX commands in reports

Search by task

task -> command -> example

Start with the task you need, then check the command, function, or shortcut syntax before using it in a real workflow.

Check context

version + module + units

Software behavior can change by version, workspace, add-in, toolbox, shell, or engineering unit system.

Verify output

example -> small test -> real work

Use the examples as starting patterns and confirm results with a small test file, sample model, or known calculation.

Document assumptions

inputs + method + result

Record the inputs, method, version, and assumptions so engineering results can be reviewed later.

Workflow notes

LaTeX workflow notes

Preamble

The part of a LaTeX document where document class, packages, and global settings are declared.

Environment

A structured block such as equation, table, figure, align, itemize, or tabular.

Package

An extension that adds commands or changes document behavior.

Label and reference

A pair of commands used to create stable cross-references to equations, figures, tables, and sections.
