Here are some course materials I used in spring 2024 for the combined class MATH 420 & CYBR 304.
So that the content was fresh in my mind, I created many (I'd say most) of the Julia worksheets hours before the class. Subsequently, I've attempted to improve the worksheets, but for a few (legendre2, for example), I got carried away and extended them beyond what we did in class.
For additional resources for teaching numerical analysis that I have created, see this GitHub repository.
