示例1: NormOne
//=============================================================================
double Epetra_MsrMatrix::NormOne() const {
if (NormOne_>-1.0) return(NormOne_);
if (!Filled()) EPETRA_CHK_ERR(-1); // Matrix must be filled.
Epetra_Vector * x = new Epetra_Vector(RowMatrixRowMap()); // Need temp vector for column sums
Epetra_Vector * xp = 0;
Epetra_Vector * x_tmp = 0;
// If we have a non-trivial importer, we must export elements that are permuted or belong to other processors
if (RowMatrixImporter()!=0) {
x_tmp = new Epetra_Vector(RowMatrixColMap()); // Create temporary import vector if needed
xp = x_tmp;
}
int i, j;
for (i=0; i < NumMyCols_; i++) (*xp)[i] = 0.0;
for (i=0; i < NumMyRows_; i++) {
int NumEntries = GetRow(i);
for (j=0; j < NumEntries; j++) (*xp)[Indices_[j]] += fabs(Values_[j]);
}
if (RowMatrixImporter()!=0) x->Export(*x_tmp, *RowMatrixImporter(), Add); // Fill x with Values from temp vector
x->MaxValue(&NormOne_); // Find max
if (x_tmp!=0) delete x_tmp;
