What does cart2sph compute az,el,r or theta,phi,r

I've seen both in the function syntaxes. az,el,r theta,phi,r

I'm guessing it is the former but I wanted to be sure.

Hi William,

it's az and el.

[a b r] = cart2sph(0,1,0)
  a =  1.5708
  b =  0        % elevation 
  r =  1
[a b r] = cart2sph(0,0,1)
  a =  0
  b = 1.5708    % elevation   
  r =  1

I see elevation as an unfortunate choice compared to measuring angle down from the z axis, but it is what it is.

Thank You Mr. Goodmanson
