print n*m matrix in matlab

Question

In MATLAB I'm printing a very large matrix this way:

fid = fopen('c:\\OUTPUT.txt','wt');
fprintf(fid,'%f\t',T');
fclose(fid);

But this is not right! I want to print it like this:(\t between them and \n at the end of row)

1   2   3
4   5   6
7   8   9
10  11  12

I searched and found If it was 3*3 this was fine:

fprintf(fid,'%f %f %f\n',T');

But I in my case size change...

Answer 1

You may also want to look at dlmwrite

You can set delimiters, precision, etc.

dlmwrite('myfile.txt', M, 'delimiter', '\t', 'precision', 6)

Where M is your matrix.
