◆ get_subblock()

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.

◆ schmidt_orthog()

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.

◆ schmidt_orthog_tol()

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.
