Numerical Computing in Julia

by Martin D. Maas, Ph.D

This is an expanding series of tutorials of numerical computing in Julia.

Interpolation, Integration, Least Squares, and more...


This tutorial series is an introduction on programming and understanding numerical methods in Julia. We will cover several topics.

Basic familiarity with Julia and VSCode is assumed. If you are a beginner, you can check out my series on Julia Programming Tutorial

I’ve also moved my chapter on the FFT to a separate, dedicated tutorial: Using the Fast Fourier Transform.

Best Julia Packages for Numerical Computing

Here is an opinionated and incomplete list of some of the best packages for numerical computing in Julia.
