1. For the PC version:
Move to the appropriate directory: chap_1, chap_2, ... etc.
For the Macintosh version:
Move to the appropriate folder: chap_1, chap_2, ... etc.
2. All of the algorithms for the text have been coded in
Matlab's programming language and stored as subroutines.
The example files for chap_1 are named a1_1.m, a1_2.m, ... etc.
For Chapter 1 the examples are illustrations of the theorems.
3. The textbook discusses the following algorithm:
Algorithm 3.1 (Back Substitution).
Section 3.3, Upper-Triangular Linear Systems, Page 145
This solves upper-triangular linear systems AX = B.
A is an n x n matrix, B is an n-dimensional vector.
To run the example for Algorithm 3.1 the user needs to use the script file
named a3_1.m. This is accomplished by executing the Matlab command:
4. The Matlab script in a3_1.m will call the subroutine named backsub.m
which is included in the sub directory or folder named chap_3.
