This matlab function quickly calculates (by matrix multiplication) the array factor of a discrete 1D, 2D or 3D array with isotropic elements of any shape. Input consists of x, y and z position of elements/sensors/microphones, the weight associated with each element, wave frequency and wave speed, and steering angles.
