How do I make multiple variables into one csv file?

Hi everyone,

Probably a simple question, but I have about 9 variables that are all separated that I would like to compact into a single CSV file with the variable names as headers. Is there an easy function to do this so that I can load the data outside of Matlab?

See the first example on writing a text file in the help for writetable(). It does exactly what you want.

writetable(yourTable, filename);

Though now when I'm trying to make the separate arrays into a table, I'm getting the following error. Undefined function 'table' for input arguments of type 'double'.

Then you must have an old version of MATLAB, earlier than R2013b. So you can simply use fopen(), fprintf(), and fclose(). Examples are in the help. It's not hard like 3-5 lines of code.
