Positions of array elements



POS = getElementPosition(H) returns the element positions in the array H.


collapse all

Create an array with two copies of a 3-element ULA, and obtain the positions of the elements.

subarrays = phased.ReplicatedSubarray('Subarray',...
    phased.ULA('NumElements',3),'GridSize',[1 2]);
pos = getElementPosition(subarrays)
pos = 3×6

Input Arguments

collapse all

Array object consisting of replicated subarrays, specified as a phased.ReplicatedSubarray System object.

Output Arguments

collapse all

Element positions in array, returned as 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].
