Exporting a matrix tab separated

Hi, my name is Nahuel and I had a lot of troubles trying to export a 3 column matrix in a txt ASCII tab separated file with that form

  500.000000  500.000000  5.000000
  500.000000  500.000000  5.000000
  500.000000  500.000000  5.000000
  500.000000  500.000000  5.000000

It means tab column tab column tab... with 6 decimal numbers. I have tried with save and dlmwrite but the matlab hate's me :(

Try dlmwrite() of your matrix, with delimiter set to '' (the empty string), and precision set to '\t%.6f'. I cannot promise that it will allow the precision to start with a tab.

If you did not need the leading tab, you would be more secure with delimiter set to '\t' and precision set to '%.6f'

[Nahuel]

you say something like dlmwrite('myfile.txt', M, 'delimiter', '', 'precision', '\t%.6f')?? I need the leading tab

[Walter Roberson]

Yes, try that dlmwrite()

Or directly without DLMWRITE:

X = rand(4, 3);
Fmt = [repmat('%.6f\t', 1, size(X, 2)), '\n'];
fid = fopen(FileName);
if fid == -1, error('Cannot open file'); end
fprintf(fid, Fmt, transpose(X));
fclose(fid);
