Hi ,

I'm trying to build a very complicated function :) that looks like :

A = dlmread('testmatrix.txt',',');
Result = A*A ; 
dlmwrite ('result.txt',Result,'newline','pc');

I got some questions about the dlmwrite function :

1) where does the 'result.txt' goes ? 2) I'm keep getting errors like : Could not open file result.txt

my goal is to use this function to write to the relative path where the m file is located.

thanks . Yuri

result.txt will go into your current directory. I.e., it will go into what this command shows:

cd

Do you have write permission in this directory?
