getElementPosition

System object: phased.ULA
Package: phased

Positions of array elements

Syntax

pos = getElementPosition(sULA)
pos = getElementPosition(sULA,elemidx)

Description

pos = getElementPosition(sULA) returns the element positions of the phased.ULA System object™, sULA. pos is a 3-by-N matrix, where N is the number of elements in sULA. Each column of pos defines the position of an element in the local coordinate system taking the form[x;y;z]. Units are meters. The origin of the local coordinate system is the phase center of the array.

pos = getElementPosition(sULA,elemidx) returns only the positions of the elements that are specified in the element index vector elemidx. This syntax can use any of the input arguments in the previous syntax.
