abdulkarim - you can use strfind or regexp. If the former you could do something like

 eAddr = 'baashe@hotmail.com';
 idx   = strfind(eAddr,'@');
 if ~isempty(idx)
     domain = eAddr(idx+1:end);
 end

Use strfind(). Be sure to make your code robust enough to handle missing @ symbols, and check if @ is in there with isempty.

email = 'baashe@hotmail.com'
atIndex = strfind(email, '@');
if ~isempty(atIndex)
        % It's a valid address.  Extract the domain.
  domain = email(atIndex+1:end);
  message = sprintf('The domain is %s', domain);
  uiwait(helpdlg(message));
else
  % Not a proper email address.
  warningMessage = sprintf('%s is not a proper email address', email);
  uiwait(warndlg(warningMessage));
end
