function varargout = camupm(lat,long)
%CAMUPM Camera UpVector from geographic coordinates.
%
%   CAMUPM(lat,long) sets the axes CameraUpVector property of the
%   current map axes to the position specified in geographic coordinates. 
%   The inputs lat and long are assumed to be in the angle units of the 
%   current map axes. 
%
%   [x,y,z] = CAMUPM(lat,long) returns the camera position in the
%   projected cartesian coordinate system.
