function Angles=EOF_test(A,z);
% This function takes the patterns in matrix A.
% A is a matrix with three dimensions. 
% The first dimension is the number of pattern sets
% The second second is the number of points in each pattern set
% The  third dimension is the patterns number within the patterns set
%
% Angles between all the subspace are compared and stored in a matrix
% called Angles and they are measured in radians.
% z is number of EOFs to take into account.
