Thread Subject: How do I add header information to a matric when using the writng to file?

I have a 201 x 7 numerical matrix that I want to write to file. Format doesn't really matter provided I can open it in excel (csv is probablt best, but could be ASCII, text, dlm, etc). How do I add header information for each column to the matric when I write the file? Thanks.

Use xlswrtite function. Wrtie descritpions of colomns in first row.
Using cell arays will allow you to add stings and numbers. Example:
M={'col1','col2';10,12};
xlswrite('tmp_xls_file',M);

If you write a CSV file, it will be fast, portable (non-windows) and simple:
fprintf(...,'field #1, field #2, ...');
fprintf(...,data)

You can also use dlmwrite for this
