BVSVDMethod#

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
