Hi,

I have a matrix that I would like to write to a text file. I need however to add a title and some comentary at the top of the text file before the matrix I have is written. I can't seem to find a method to do this. Any Suggestions?

Thanks

doc fprintf % you can write whatever you wish however you wish

Isn't a generic textwrite() function similar to textread(), though, so
you'll have to "roll your own".

Piecing together some examples from "doc fprontf", we have:

x = 0:.1:1;
y = [x; exp(x)];
fid = fopen('exp.txt', 'wt');
fprintf(fid,'It''s Friday.\n');
fprintf(fid, '%6.2f %12.8f\n', y);
fclose(fid)

type exp.txt

It's Friday.
