This is a site for Courant's undergraduate course in Numerical Analysis.

**Instructor**: Charles Puelz

**Location and Time**: Tues and Thurs, 11 - 1215pm, CIWW 201

**TA**: Tristan Goodwill. Session is held **Friday, 11 - 1215pm, CIWW 517**

**Grader**: Runxi Bai

**Syllabus**: syllabus.pdf

We will be working mainly from the book *An Introduction to Numerical Analysis* by Suli and Mayers.

I’ll post pdfs of my notes, along with some sample Matlab codes. Some of the codes are from Georg Stadler… thanks!
