SCMatrix* sc::DistSCMatrix::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::DistSCMatrix::local_blocks (SCMatrixSubblockIter::Access) [virtual]

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

Implements sc::SCMatrix.

void sc::DistSCMatrix::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::DistSCMatrix::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.
