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.
