SCMatrix* sc::BlockedSCMatrix::get_subblock (int br, int er, int bc, int ec) [virtual]

Return a subblock of this. The subblock is defined as the rows starting at br and ending at er, and the columns beginning at bc and ending at ec.

Implements sc::SCMatrix.

Ref<SCMatrixSubblockIter> sc::BlockedSCMatrix::local_blocks (SCMatrixSubblockIter::Access) [virtual]

Returns iterators for the local (rapidly accessible) blocks used in this matrix.

Implements sc::SCMatrix.

void sc::BlockedSCMatrix::schmidt_orthog (SymmSCMatrix *, int n) [virtual]

Schmidt orthogonalize this. S is the overlap matrix. n is the number of columns to orthogonalize.

Implements sc::SCMatrix.

int sc::BlockedSCMatrix::schmidt_orthog_tol (SymmSCMatrix *, double tol, double * res = 0) [virtual]

Schmidt orthogonalize this. S is the overlap matrix. tol is the tolerance. The number of linearly independent vectors is returned.

Implements sc::SCMatrix.

void sc::BlockedSCMatrix::svd_this (SCMatrix * U, DiagSCMatrix * sigma, SCMatrix * V) [virtual]

Compute the singular value decomposition for this, possibly destroying this.

Reimplemented from sc::SCMatrix.
