I am using GNU Octave, version 2.1.72 (i486-pc-linux-gnu). Codes? Hmm...I
guess the only problem was creating a huge matrix of 100x5000 to store the
data that causes the problem. Prior to this computation, the system was also
computing a some codes.

%for x = 1 : rowNum
%       nowColSize = columns(deref(strImage,1,x));
%       tmp = deref(strImage,1,x);      
%       for y = 1 : bigCol
%               if(y <= nowColSize)
%                       matData(x,y) = tmp(1,y);
%               endif
%               if(y == nowColSize)
%                       break;
%               endif
%       endfor
%endfor
