BVOrthogBlockType#

Determines the method used in block orthogonalization (simultaneous orthogonalization of a set of vectors).

Synopsis#

typedef enum { BV_ORTHOG_BLOCK_GS,
               BV_ORTHOG_BLOCK_CHOL,
               BV_ORTHOG_BLOCK_TSQR,
               BV_ORTHOG_BLOCK_TSQRCHOL,
               BV_ORTHOG_BLOCK_SVQB     } BVOrthogBlockType;

Values#

BV_ORTHOG_BLOCK_GS - Gram-Schmidt, column by column
BV_ORTHOG_BLOCK_CHOL - Cholesky QR method
BV_ORTHOG_BLOCK_TSQR - Tall-Skinny QR method
BV_ORTHOG_BLOCK_TSQRCHOL - TSQR, but computing the triangular factor only
BV_ORTHOG_BLOCK_SVQB - SVQB method
