fprrintf MATLAB R2013a not working

Hey everyone,

I'm sending my values to a txt file in MATLAB R2013a but the txt file remains empty and all the printing is done in the command window! Does anyone know why is this happening? And how can I print the values in a txt file?

fid = fopen('Code.txt','w');
fprintf('start a new cycle \n');
fprintf('t = %0.5f\t total_diss %0.5f\n', t, total_diss)
fclose(fid);

For those reading this question, this is covered in the fprintf documentation:

Syntax

fprintf(fileID,formatSpec,A1,...,An)

...

Input Arguments

fileID — File identifier1 (default) | 2 | scalar

File identifier, specified as one of the following:

• A file identifier obtained from fopen.
• 1 for standard output (the screen).
• 2 for standard error.

Yasmine, use

 fid = fopen('Code.txt','w');
 fprintf(fid,'start a new cycle \n');
 fprintf(fid,'t = %0.5f\t total_diss %0.5f\n', t, total_diss)
 fclose(fid);

instead. Note that you need to add the fileID fid to the fprintf command.
