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;

Values

• 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 communication-avoiding Arnoldi
