pseudo-inverse rank r A - UvA · eqs. (2.50) and (2.63)): = A From eqs. (2.78) and (2.80), we obtain (2.80) (2.81) The rank and the generalized inverse of a matrix are well defined

pseudo-inverse rank r

with SVD, notmuch harder forgeneral A (2.121)
save for when we need it
no restrictions on A !
rotational part of Procrustes method
derive these from 2.164(see (2.1)...)

directsum =stacking
what will be the geometricalsignificance of the matrix norms?
moral: tensors can be recast(for computations, not meaning)
derive the 2!
