LaTeX

LaTeX is a document preparation system built on TeX, widely used to produce high-quality technical and scientific documents. It lets authors write plain-text source with markup for structure, equations, references, tables, and figures, then compile it to output formats such as PDF.

It is used by researchers, academics, engineers, and publishers who need precise control over layout and consistent handling of complex content. A distinguishing trait is its strong support for mathematical typesetting and automated document elements such as bibliographies, cross-references, and numbering.
