Transform spherical coordinates to Cartesian
[x,y,z] = sph2cart(azimuth,elevation,r)
[x,y,z] = sph2cart(azimuth,elevation,r) transforms the corresponding elements of spherical coordinate arrays to Cartesian, or xyz, coordinates. azimuth, elevation, and r must all be the same size (or any of them can be scalar). azimuth and elevation are angular displacements in radians. azimuth is the counterclockwise angle in the x-y plane measured from the positive x-axis. elevation is the elevation angle from the x-y plane.
