- Week 6:
- The midterm review session will be held on Monday Feb. 11 from 5.30 to 6.30 at MS6627.
- New office hours:
- Wednesday 1 to 2 at MS3974 (Student Math Center)
- Wednesday 3 to 4 at MS2925 (Math 135B)
- Thrusday 12 to 1 at MS6627 (Math 151B)

- Week 4:
- I will be out of town from Jan. 25 to Feb. 5 (both included). My office hours for Monday 1/28 and Wednesday 1/30 are cancelled (I will schedule extra office hours the following week). Mark Moelich will hold the discussion session at the regular time and location.

- Week 10:
**GOOD LUCK IN YOUR FINAL!** - Week 9:
**Homework #7 Computational Problem CORRECTED!**. Following, are some links to the solution of problem 6 in section 8.1. Although you are not supposed to solve this problem using matlab, problem 5 (the one you are supposed to solve using matlab) is very similar, so this should help you.- This file contains the matlab commands i used to solve the problem. The file does not include comments, if you have questions about any particular command, email me the command and your question.
- Plot of the given data and its linear fitting.
- Plot of the given data and its exponential fitting (f(x)=b*exp(a*x)).
- Plot of the given data and its polynomial fitting (f(x)=b*x^a).
- Plot of the given data and its exponential fitting (f(x)=b*a^x).

- Week 8:
**Homework #6 Computational Problem**.- plot of the solution to computational problem # 2 with N=20.

- Week 7:
**Homework #5 Computational Problem**. Your code for the midpoint method for a scalar equation should work with minor modifications.- Sample code for vector function
**F**(**y**,t), where**y**is a vector. - Something similar to these lines of code should help in making your previous midpoint algorithm work. (corrected)
- Phase plane plots at times: t =5, t=10, and t=12.

- Sample code for vector function
