LaTex Macros for Technical Writing

LaTex Macros for Technical Writing

Writing a technical paper or thesis can be hard. But, it shouldn’t be harder than it needs to.

The typesetting system LaTex has become the de-facto standard for writing technical content, especially for those manuscripts which require an army of mathematical notation, variables, and operators.

Here, I like to offer another helpful trick to make your writing more consistent by using macros. Instead of typing out the equations directly, e.g., F = m a, it might be more informative to type the semantics \force = \mass \acceleration. To make this work, the macros need to be defined in the document preamble:


This approach has several important advantages:

  • Variable names and notation are independent of meaning
  • Variable names can be easily changed later when a name collision occurs
  • Consistent formatting of operators, e.g., bold for matrices
  • Variables and operators are easily searchable in the document
  • Enforces interpreting mindset

Naturally, these macros can be nested to create more highlevel expressions, e.g., \force = \mass \timeDerivative{ \speed }. The additional definitions are:


Besides newcommand, there are a few other helpful types of macros:

  • DeclareMathOperator for operator notations like min, max or sign
  • DeclarePairedDelimiter for any delimiter operators like brackets, norms or rounding

All these can be stored away into a .sty file and reused for your next manuscript. By this, you develop over time a set of useful notations and variable conventions and reach the level of consistency you require for your few-hundred-page thesis. A complete example of latex file with notation macros can be downloaded here:



At first, this might look like extra work, but once you’re at the end of the writing, you will highly appreciate the added flexibility. Happy writing!
