%sample code to read in text input using load, dlmread and textscan along
%with sample code to write text using dlmwrite and fprintf


clear all;

%output an array to a file using dlmwrite
foo = rand(10,5);

%use default delimiter, row and column starting
dlmwrite('sample_text.txt', foo);

%or to use tab as the delimiter
dlmwrite('sample_text_2.txt',foo,'delimiter','\t');

%or to use a single space as the delimiter
dlmwrite('sample_text_3.txt',foo,' ',0,0);


%output an array using fprintf
x = 0:.1:1;
foo = [x; exp(x)];

fid = fopen('sample_text_4.txt','w');
fprintf(fid,'%f \n', foo);
fclose(fid);



%read in a text file using load
data = load('sample_text.txt');
%load infers the delimiter from the file

%read in same text file using dlmread
%need to specify the delimiter when using dlmread
%dlmread is more flexible than load
data_2 = dlmread('sample_text_2.txt', '\t', 0, 0);

%read in a variable whitespace delimited file using dlmread
data_3 = dlmread('sample_text_var.txt', '', 0, 0);

%ignore the first three lines
data_4 = dlmread('sample_header.txt', '\t', 3, 0);

%read in a file using textscan
fid = fopen('sample_strings.txt', 'r');
cell_data = textscan(fid,'%s',12);
fclose(fid);
