Abstract

We have seen in the last section that the difficulty in identifying real physical patterns from EOF stems from their orthogonal nature. Orthogonality translates into the fact that typical patterns appear in secondary (higher order) EOF. Very often the first EOF has little structure, the second has a positive and a negative center, the third more centers and so on, in a way so as to maintain orthogonality.
