%   INSTRUCTIONS
% 
% 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 2.1 (Fixed Point Iteration). To find a solution to the equation
%     x  =  g(x)   by starting with  p(0)  and iterating   p(n+1)  =  g(p(n)).
% 
%     To run the example for Algorithm 2.1 the user needs to use the script file 
%     named a2_1.m.  This is accomplished by executing the Matlab command:
% 
%     a2_1 
% 
% 4. The Matlab script in  a2_1.m  will call the subroutine named  fixpt.m 
%     which is included in the sub directory or folder named  chap_2.
%     Also, for the above example, the following function must exist as a 
%     M-file named  g.m.
% 
%     function y = g(x)
%     y = 1 + x - x.^2 ./4;
% 
%     For demonstration purposes, I have used a special Matlab feature which 
%     opens and writes to a file to ensure that the above M-file  g.m  will exist
%     in the proper sub directory or folder along with the script file a2_1.m  and
%     function (subroutine) file  fixpt.m.  These commands are:
% 
%     delete g.m
%     diary g.m; disp('function y = g(x)');...
%                disp('y = 1 + x - x.^2 ./4;');...
%     diary off;
% 
% 5. Once the process of writing a function M-files has been mastered,
%     it is not necessary to use the diary commands mentioned above 
%     to create this function M-file named g.m.  The user can then
%     delete these lines from the script file  a2_1.m.
