◆ build() [1/2]

std::pair< std::unique_ptr< TClusterBasis< T > >, std::unique_ptr< TClusterBasis< T > > > build ( const TCluster rowct,
const TCluster colct,
const TMatrix M,
const TTruncAcc acc 
) const

Build row and column cluster basis for H matrix M over given cluster trees rowct × colct. The accuracy of the cluster basis is determined by acc

◆ build() [2/2]

std::pair< std::unique_ptr< TClusterBasis< T > >, std::unique_ptr< TClusterBasis< T > > > build ( const TMatrix M,
const TTruncAcc acc 
) const

Build row and column cluster basis for H matrix M. The accuracy of the cluster basis is determined by acc
