Positions of the elements of a sensor array specified as a 1-by-Nvector, a 2-by-Nmatrix, or a 3-by-Nmatrix. In this vector or matrix,Nrepresents the number of elements of the array. Each column ofposrepresents the coordinates of an element. Ifposis a 1-by-Nvector, then it represents they-coordinate of the sensor elements of a line array. Thexandz-coordinates are assumed to be zero. Whenposis a 2-by-Nmatrix, it represents the(y,z)-coordinates of the sensor elements of a planar array. This array is assumed to lie in theyz-plane. Thex-coordinates are assumed to be zero. Whenposis a 3-by-Nmatrix, then the array can have an arbitrary shape. Sensor positions are in terms of signal wavelength.

Example:[0,0,0; 0.1,0.4,0.3; 1,1,1]

Data Types:double

Arrival directions of incoming signals specified as a 1-by-Mvector or a 2-by-Mmatrix, whereMis the number of incoming signals. Ifangis a 2-by-Mmatrix, each column specifies the direction in azimuth and elevation of the incoming signal[az;el]. The azimuth angle must lie between –180° and 180° and the elevation angle must lie between –90° and 90°. The azimuth angle is the angle between thex-axis and the projection of the arrival direction vector onto thexyplane. It is positive when measured from thex-axis toward they-axis. The elevation angle is the angle between the arrival direction vector andxy-plane. It is positive when measured towards thezaxis. Ifangis a 1-by-Mvector, then it represents a set of azimuth angles with the elevation angles assumed to be zero. Angle units are specified in degrees.

Data Types:double

Number of bits used to quantize the phase shift in beamformer or steering vector weights, specified as a non-negative integer. A value of zero indicates that no quantization is performed.
