CS 221 Fall 2011
Things to Know for the third in-class quiz:

0. Your section number, section time, and TA's name

1. What type of plot to use in various situations.  E.g., to visualize
measured data against a theoretical prediction, us a scatter plot with
a "theory" curve.  To compare two time series, use a bar chart.  To
visualize a distribution, a histogram is usually best.  Etc. (Text
Chapter 5.)

2. How to spot common errors in MATLAB scripts.  (E.g., array indices
out of bounds, loops that fail to terminate, uninitialized variables,
etc. See problems at the end of chapter 4.)

3. How to simulate MATLAB execution of scripts, especially with loops
and array processing.

4. Know the characteristics of the various root-finding methods
discussed in class, including bisection, Newton's, Fixed-point, and
MATLAB's roots() function.  You should also know the basic outline of
the computations required for each of these.

5. Know your matrix operations, including matrix multiplication.  Know
the MATLAB operators on matrices.

6. Be able to describe how to find roots using Excel.

7. Be able to discuss "convergence" and "divergence" of root-finding
methods.

8. Know how to use MATLAB to solve systems of simultaneous equations
represented by arrays.
