# A Gentle Introduction to Linear Algebra

Last Updated on August 9, 2019

### What is Linear Algebra?

Linear algebra is a field of mathematics that is universally agreed to be a prerequisite to a deeper understanding of machine learning.

Although linear algebra is a large field with many esoteric theories and findings, the nuts and bolts tools and notations taken from the field are practical for machine learning practitioners. With a solid foundation of what linear algebra is, it is possible to focus on just the good or relevant parts.

In this tutorial, you will discover what exactly linear algebra is from a machine learning perspective.

After completing this tutorial, you will know:

- Linear algebra is the mathematics of data.
- Linear algebra has had a marked impact on the field of statistics.
- Linear algebra underlies many practical mathematical tools, such as Fourier series and computer graphics.
