Implement matrix multiplications for a vector using the PointerMatrixBase functionality. Objects of this class can be used in block matrices.
Implements a matrix with image dimension 1 by using the scalar product (vmult()) and scalar multiplication (Tvmult()) functions of the Vector class.
Definition at line 355 of file pointer_matrix.h.
| PointerMatrixVector< number >::PointerMatrixVector | ( | const Vector< number > * | M = 0 | ) |
Constructor. The pointer in the argument is stored in this class. As usual, the lifetime of *M must be longer than the one of the PointerMatrix.
If M is zero, no matrix is stored.
Definition at line 860 of file pointer_matrix.h.
| PointerMatrixVector< number >::PointerMatrixVector | ( | const char * | name | ) |
Constructor.
This class internally stores a pointer to a matrix via a SmartPointer object. The SmartPointer class allows to associate a name with the object pointed to that identifies the object that has the pointer, in order to identify objects that still refer to the object pointed to. The name argument to this function is used to this end, i.e., you can in essence assign a name to the current PointerMatrix object.

| PointerMatrixVector< number >::PointerMatrixVector | ( | const Vector< number > * | M, |
| const char * | name | ||
| ) |
Constructor. M points to a matrix which must live longer than the PointerMatrix.

Reset the object to its original state.

Return whether the object is empty.

Assign a new matrix pointer. Deletes the old pointer and releases its matrix.
Definition at line 888 of file pointer_matrix.h.

inlinevirtual |
Matrix-vector product, actually the scalar product of src and the vector representing this matrix.
The dimension of dst is 1, while that of src is the size of the vector representing this matrix.
Implements PointerMatrixBase< Vector< number > >.
Definition at line 906 of file pointer_matrix.h.

Transposed matrix-vector product, actually the multiplication of the vector representing this matrix with src(0).
The dimension of src is 1, while that of dst is the size of the vector representing this matrix.
Implements PointerMatrixBase< Vector< number > >.
Definition at line 918 of file pointer_matrix.h.
