% script to create a table for the function y = exp(x)
% and store it in a data file
% declare x and y as row vectors
x = 0:.1:1; 
y = [x; exp(x)];

% open the data file to write - w for write, t for text
 fid = fopen('exp.txt','wt');

% formatted print - "vectorized"... don't need loop structure!
fprintf(fid,'%6.2f %12.8f\n',y);

%close the file
fclose(fid);
