Syntax

POS = getElementPosition(H)
POS = getElementPosition(H,ELEIDX)

Description

POS = getElementPosition(H) returns the element positions of the URA H. POS is a 3-by-N matrix where N is the number of elements in H. Each column of POS defines the position of an element in the local coordinate system, in meters, using the form [x; y; z].

For details regarding the local coordinate system of the URA, enter phased.URA.coordinateSystemInfo.

POS = getElementPosition(H,ELEIDX) returns the positions of the elements that are specified in the element index vector, ELEIDX. The index of a URA runs down each column, then to the next column to the right. For example, in a URA with 4 elements in each row and 3 elements in each column, the element in the third row and second column has an index value of 6.
