Hi Scott, the tranfsformation matrix can be obtained from SingularValueDecomposition (3. matrix). Unfortunately, people from different directions have different names for the same thing, what makes it rather confusing. Principal Components are the same like singular vectors or (under certain circumstances) Eigenvectors.
