◆ build() [1/2]

virtual TMatrix* build ( const TBlockCluster *  bct,
const TTruncAcc &  acc 
) const
inlinevirtual

build low rank matrix for block cluster bct with rank defined by accuracy acc

Reimplemented in THCA< T >, TACA< T >, TRRQRLRApx< T >, TRandSVDLRApx< T >, and TSVDLRApx< T >.

◆ build() [2/2]

virtual TMatrix* build ( const TBlockIndexSet &  bis,
const TTruncAcc &  acc 
) const
pure virtual

build low rank matrix for block index set bis with rank defined by accuracy acc

Implemented in THCA< T >, TACA< T >, TRRQRLRApx< T >, TRandSVDLRApx< T >, TSVDLRApx< T >, TDenseLRApx< T >, and TZeroLRApx.
