For confirmity with the atan documentation I used

Compute atan (@var{y} / @var{x}) in degrees for corresponding elements

I made the change on the stable branch here (http://hg.savannah.gnu.org/hgweb/octave/rev/ea1253f05dd3).

Marking as fixed and closing report.

Yes, either 'atand(y/x)' or 'atan2(y,x)' is OK, but not 'atan2(y/x)',
because 'atan','atand' must accept one input argument, 'atan2','atan2d' must accept two input arguments.

In mathematics, it atan2(y,x)=tan-1(y/x).
Here it showing,
'atan2d ( y, x ):
Compute atan2 (y / x) in degrees for corresponding elements from y and x.'
Here 'atan2' should be 'atand',else everything is fine.It is just a typing mistake.
