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.

Added possibility to have 3D arrays as input also

Added circular array in example. plotBeampattern3D now displays 0 dB as highest point in scale.

Changed some variable names to be more consistent with other files

Added plotBeampattern and plotBeampattern3D

Changed title

Added pdf with mathematical explanation
