Explanation / Answer

Dear Ron,

the way u are dealing with csv files is wrong.

u are handling them in same way as text files in matlab.

this is not the way to wrtie to csv files.

fprintf is supposed to use with csv files that y u r getting error.

plz change your lineto this

fopen('My Documentsproj2.txt', 'w');

or

use xlswrite  

for moreinfo   plz go thorugh this.
