Path loss and phase change for RF propagation ray

`[`

returns the path loss in dB and phase shift in radians based on the properties specified by
`pl`

,`phase`

] = raypl(`ray`

)`ray`

. The path loss and path shift computations consider the free
space loss and reflection loss derived from the propagation path, reflection materials, and
polarizations. The function accounts for geometric coupling between horizontal and vertical
polarizations only when both transmit and receive antennas are polarized. For more
information, see Path Loss Computation.

`[`

calculates the path loss and phase shift with additional options specified by one or more
name-value pair arguments.`pl`
