matlab unable to write to text file

Question

I am trying to write to a text file "result.txt" using the following matlab code in ubuntu 13.10

fid = fopen('/home/gaurav/matlab/OCR/result.txt','wt');
fprintf(fid,'asdasd');
fclose(fid)

I have changed the permission of file to 777, but nothing is happening.

I changed the 3rd line to

fprintf(fid,'%s','asdasd'); 

it worked, but now I changed it to

I am sorry it worked the first time, but after modifying it

fid = fopen('result.txt','wt+');
s='Allison Jones';
d='Development  ';
fprintf(fid,'%s\n',s);
fprintf(fid,'%s\n',d);
fclose(fid);
clc;clear;

the file is not being modified.

Answer 1

Instead of using only the file name in

fid = fopen('result.txt','wt+');

use the complete directory path

fid = fopen('/home/gaurav/matlab/OCR/result.txt','wt+');
