I have updated the textbook _Fundamentals of Numerical Computation_, coauthored with Rich Braun, to be an online-first resource at [fncbook.com](https://fncbook.com).
The book is intended for a standalone course or two-semester sequence in numerical computation for undergraduates. It assumes prior experience with calculus, (basic) differential equations, and computing.
Each of the 169 code-based examples is presented for Julia, MATLAB, and numpy/scipy. (I have never taught using the Python versions, but the others are time-tested.) Each section has multiple written and coding exercises.
Print versions for MATLAB (2017) and Julia (2022) are still available at the [SIAM bookstore](https://epubs.siam.org/action/doSearch?AllField=Driscoll&PubTypeOr=105&PubTypeOr=109&enableConditionalBoosting=true&pt=book). Changes from the Julia print edition are mostly typo fixes and formatting, except that I split the book’s pedagogical [collection of functions](https://github.com/fncbook/FNCFunctions.jl) into a package separate from all the more familiar packages that are used throughout the book.

This is really timely, since I’m co-teaching a numerics class this spring at MIT and we wanted to show both Python and Julia examples. Thanks for sharing!

Great books!
This is a really minor thing, but I noted this quote on [https://fncbook.com/overview-2:](https://fncbook.com/overview-2:)
The “hit her” kind of seems to imply Han hit a woman (Leia), which I found really strange, especially to use as a quote. Turns out the actual quote is “must have hit pretty close to the mark…” (i.e. without the first “her”), [https://getyarn.io/yarn-clip/65d084df-4427-4b2c-97d5-49be36177873](https://getyarn.io/yarn-clip/65d084df-4427-4b2c-97d5-49be36177873) 🤷♂️

Huh. I thought I vetted all of those against the scripts a long time ago, but you’re right. Thanks.
I still say Han shot first, though.

**Update for Spring 2026**
I know the online book has now been used by instructors at U of Delaware (my home institution), MIT, the U of Virginia, and U of Florida. I also see (non-personally-identifiable) significant visits from Baltimore, Provo and Kansas City, plus the Netherlands, Vietnam, China, Turkey, South Africa, and more.
- In addition to the trilingual version at [fncbook.com](http://fncbook.com), there are also single-language versions for [Julia](https://fncbook.com/julia), [Matlab](https://fncbook.com/matlab), and [Python](https://fncbook.com/python). Same content, less clutter. These are derived from the root version on each build, so they should stay in sync.
- New animation outputs in Chapter 6 on initial-value problems.
- Video walkthroughs for all the Julia demo examples, through Chapter 6. Currently, the first two chapters are posted, but I plan to have them all up before the fall semester starts.
- Streamlined description of [how to set up Julia](https://fncbook.com/julia/setup) for the book. (The book is agnostic regarding the use of environments such as Jupyter, Pluto, BonitoBook, etc.)
- Updated for the latest versions of DifferentialEquations dependencies.
- Claude was used to help locate and fix typos and a few unclear proof steps.
