Directivity of replicated subarray

`D = directivity(H,FREQ,ANGLE)`

D = directivity(H,FREQ,ANGLE,Name,Value)

`D = directivity(`

returns
the Directivity (dBi) of a replicated
array of antenna or microphone element, `H`

,`FREQ`

,`ANGLE`

)`H`

, at
frequencies specified by `FREQ`

and in angles of
direction specified by `ANGLE`

.

The integration used when computing array directivity has a minimum sampling grid of 0.1 degrees. If an array pattern has a beamwidth smaller than this, the directivity value will be inaccurate.

`D = directivity(`

returns
the directivity with additional options specified by one or more `H`

,`FREQ`

,`ANGLE`

,`Name,Value`

)`Name,Value`

pair
arguments.
