[az,el] = view
The position of the viewer (the viewpoint) determines the orientation of the axes. You specify the viewpoint in terms of azimuth and elevation, or by a point in three-dimensional space.
view(az,el) and view([az,el]) set the viewing angle for a three-dimensional plot. The azimuth, az, is the horizontal rotation about the z-axis as measured in degrees from the negative y-axis. Positive values indicate counterclockwise rotation of the viewpoint. el is the vertical elevation of the viewpoint in degrees. Positive values of elevation correspond to moving above the object; negative values correspond to moving below the object.
view(ax,...) uses axes ax instead of the current axes.
View the object from directly overhead.
az = 0; el = 90; view(az, el);
Set the view along the y-axis, with the x-axis extending horizontally and the z-axis extending vertically in the figure.
Rotate the view about the z-axis by 180º.
az = 180; el = 90; view(az, el);
Azimuth is a polar angle in the x-y plane, with positive angles indicating counterclockwise rotation of the viewpoint. Elevation is the angle above (positive angle) or below (negative angle) the x-y plane.
