When I read a matrix stored in a text file, the values are shuffled about

fid = fopen('mat.txt','r');
matrix = fscanf(fid,'%g',[6 4]);

Could someone explain why this happens? or suggest a better method?

The matrix consists of 1's and 0's

Try fread() instead of fscanf(). Not sure that's the problem though. Are you sure you're not confusing (x,y) with (row, column)? That's the error most novices make. Remember (row, column) is (y,x) NOT (x,y).

Matrix in file:

0  1  0  0  
1  1  0  0  
1  1  1  0  
0  1  1  1  
0  1  0  1  
0  0  0  1

fscanf:

       0     0     0     0
       1     0     1     1
       0     1     1     0
       0     1     1     0
       1     1     0     0
       1     0     1     1

If you're still having a problem, attach the file with the paper clip icon. Or why not use dlmread() with a delimiter of space or tab, whichever it is?
