camvaPurpose2camvaSet or query the camera view angleSyntaxDescriptioncamvacamva(view_angle)camva('mode')camva('auto')camva('manual')camva(axes_handle,...)The camera view angle determines the field of view of the camera. Largerangles produce a smaller view of the scene. You can implement zooming bychanging the camera view angle.camva with no arguments returns the camera view angle setting in the currentaxes.camva(view_angle) sets the view angle in the current axes to the specifiedvalue. Specify the view angle in degrees.camva('mode') returns the current value of the camera view angle mode,which can be either auto (the default) or manual. See Remarks.camva('auto') sets the camera view angle mode to auto.camva('manual') sets the camera view angle mode to manual. See Remarks.camva(axes_handle,...) performs the set or query on the axes identified bythe first argument, axes_handle. When you do not specify an axes handle,camva operates on the current axes.Remarkscamva sets or queries values of the axes object CameraViewAngle andCameraViewAngleMode properties.When the camera view angle mode is auto, MATLAB adjusts the camera viewangle so that the scene fills the available space in the window. If you move thecamera to a different position, MATLAB changes the camera view angle tomaintain a view of the scene that fills the available area in the window.2-68
