We will use Piazza for communication and organization. If you are registered for this class you will receive an invitation to join the course on Piazza at the beginning of the semester. Otherwise please email me and I will add you.
Various other documents and course schedule will be posted to this website.
The textbook for the course is An Introduction to Numerical Analysis, Suli and Mayers, Cambridge University Press, 2003. PDF available via NYU. Supplemental texts and references will be suggested along the way.
Relevant code examples will be posted on gitlab.com/oneilm/na18.
Important information for the course will appear on the Piazza page.
