Detailed Description

template<typename T>
class fastglmmLib::spectralDecomp< T >

Class storing matrix Z, its squared singular values (s), left singular vectors (U), and right singular vectors (V). Z can be mat or sp_mat. Default type is GENERAL for arbitrary matrix Z. If Z is a categorical design matrix, use a faster method with type CATEGORICAL.

reweight() computes the SVD of the weighted Z matrix
