getElementNormal

Normal vectors for array elements

Syntax

normvec = getElementNormal(array)

normvec = getElementNormal(array,elemidx)

Description

normvec = getElementNormal(array) returns the element normals of the System object™, array. normv is a 2-by-N matrix, where N is the number of elements in array. Each column of normv specifies the normal direction of the corresponding element in the local coordinate system in the form [azimuth;elevation]. Units are degrees. For details regarding the local coordinate system of a UCA, typeat the command line.

normvec = getElementNormal(array,elemidx) returns only the normals of the elements that are specified in the element index vector elemidx.

Input Arguments

array — Phased array System object

System object

Phased array, specified as a System object.

elemidx — Element index vector

all element indexes (default) | vector of positive integers

Element index vector, specified as a vector of positive integers each of which takes a value from 1 to N. The dimension N is the number of elements of the array.

Example: [1,2,3]

Output Arguments

normvec — Normal vector

2-by-M real-valued matrix

Normal vector of array elements, returned as a 2-by-M real matrix. Each column of normvec specifies the normal direction of the corresponding element in the local coordinate system in the form [azimuth;elevation]. If the input argument elemidx is not specified, M is the number of elements of the array, N. If elemidx is specified, M is the dimension of elemidx. Units are in degrees.
