% This is an example of a simple program, which 
% creates a table of y = 2 x2 +3.2 x - 5.6 versus x 
% as x varies between -2 and +2.
% The table is written to file polyreport.txt
% 
% open a stream for the file
table = fopen ('polyreport.txt', 'wt');
% calculate arrays
x = -2: 0.5 : +2;
y = 2 * x .^ 2 + 3.2 * x - 5.6;
% print to the screen
fprintf( '\n\n    Our results \n    x        y  \n');
fprintf( '\n %5.2f     %5.2f   ', [x ; y ]);
% print to the file too
fprintf( table ,'\n\n    Our results \n    x        y  \n');
fprintf( table , '\n %5.2f     %5.2f   ', [x ; y] );
fclose( table );
fprintf('\n\n  See also file polyreport.txt \n');
