How to change camera view with respect to the current axes coordinate system

In 3D system I want the camera to look at x-y plane so that the camera optical axis is along the z axis and the principal point is (0,0). How can i do this?

When you have a plot on a figure, you may change your viewpoint quite easily.

% get the current viewpoint
viewPt = get(gca, 'CameraPosition') 
% viewPt is a 3-element vector containing x, y, z location of the camera.
% set the camera at (0, 0, 10)
set(gca, 'CameraPosition', [0, 0, 10]);

Hope this helps.
