virtual void | MultVectorImpl (Number alpha, const Vector &x, Number beta, Vector &y) const |
Matrix-vector multiply. | |
virtual void | TransMultVectorImpl (Number alpha, const Vector &x, Number beta, Vector &y) const |
Since the matrix is symmetric, it is only necessary to implement the MultVectorImpl method in a class that inherits from this base class. | |
virtual void | ComputeRowAMaxImpl (Vector &rows_norms, bool init) const |
Compute the max-norm of the rows in the matrix. | |
virtual void | ComputeColAMaxImpl (Vector &cols_norms, bool init) const |
Since the matrix is symmetric, the row and column max norms are identical. | |

virtual void Ipopt::ZeroSymMatrix::TransMultVectorImpl | ( | Number | alpha, | |
const Vector & | x, | |||
Number | beta, | |||
Vector & | y | |||
) | const [protected, virtual] |
Since the matrix is symmetric, it is only necessary to implement the MultVectorImpl method in a class that inherits from this base class.
If the TransMultVectorImpl is called, this base class automatically calls MultVectorImpl instead.
Reimplemented from Ipopt::SymMatrix.
virtual void Ipopt::ZeroSymMatrix::ComputeRowAMaxImpl | ( | Vector & | rows_norms, | |
bool | init | |||
) | const [inline, protected, virtual] |
Compute the max-norm of the rows in the matrix.
The result is stored in rows_norms. The vector is assumed to be initialized.
Implements Ipopt::Matrix.
