function Wout = orthbeam(Win)

%ORTHBEAM Orthogonalization of beamforming weights.
%  Wout = ORTHBEAM(Win) orthogonalizes the beamforming weight vectors in Win.
%  That is, Wout'*Wout = I.
%
%  Size of Win and Wout is (M x N):
%    M = # channels.
%    N = # weight vectors.
%
%  If the beams are to close to eachother, this method does not manage to 
%  orthogonalize them. There will be no warning or error message.
