I want to make a polar plot from azimuth angles and zenith angles. I wonder in polar(theta,rho) if theta is azimuth and rho is zenith? and if they must be in radian? I also wonder how I can put change the position of the origin (0) on the circule as I want the origin to start from north and increse clockwise. I appereciate your help.

I found the answer on http://www.mathworks.com/matlabcentral/newsreader/view_thread/134222. I should use view(90,-90).

No, rho is radius. You cannot create a polar plot just from angles.
I do not see a MATLAB routine for 3D polar plots, but there might perhaps be one in the MATLAB File Exchange (FEX)

Since rho is not an angle, it is incorrect to think of it as being in degrees _or_ radians. theta must be in radians.

I see. what about the change of the origin of angle to start from north (if we assume the current origin is in east) and increases clockwise?
