Different methods for computing the SVD of a BV

Synopsis

typedef enum { BV_SVD_METHOD_REFINE,
               BV_SVD_METHOD_QR,
               BV_SVD_METHOD_QR_CAA } BVSVDMethod;

Notes

Allowed values are
BV_SVD_METHOD_REFINE  - based on the SVD of the cross product matrix S'*S, with refinement
BV_SVD_METHOD_QR  - based on the SVD of the triangular factor of qr(S)
BV_SVD_METHOD_QR_CAA  - variant of QR intended for use in cammunication-avoiding Arnoldi
