The PCA analysis is a somewhat specialised filter developed to be used
together with the Procrustes class also in VTK. It is not a "general" PCA
method that can be used on arbitrary matrices. It requires a set (not only
one) aligned datasets to work. I suggest reading the class documentation.
Furthermor, read Cootes' online report if you plan to use it for
statistical shape analysis.
