Well, from the documentation for fprintf:

"fprintf(fileID, format, A, ...) applies the format to all elements of array A and any additional array arguments in column order, and writes the data to a text file."

So it is just like going in the opposite direction to textread and seems to correspond to exactly what you asked for. Can you explain a little more what you need help with? Is it that you have to call fopen to get the fileID?

Hey .. one problem occurred when I use like this :

fprintf(fid,'SIGNIFICANCE LEVEL = .050\n');
fprintf(fid,'DF1 = %d DF2 = %d \n',df1,df2);
'\n' did not run. and all my results in text file are appeared in one line. do you know what is the problem ?

Works here (although you need an additional "\n" to terminate the last
line).

Which OS? Where's your fopen() call? If Windows and didn't, make sure
use the 't' option to specify text file...

fid=fopen('filename', 'wt'); % Need the "t" on Winders...

Just did confirmation test; on Windows w/o the 't' fprintf() did,
indeed not include the newline characters (CR/LF), simply the LF (x0A)
which isn't recognized by most Windows text tools as equivalent to the \n.

Are you possibly using Windows, and did you possibly forget to include
the 't' parameter when you opened the text file?

fopen(filename, 'wt'); %t is needed for text files
