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 338 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 805 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.
Implements PointerMatrixBase< Vector< number > >.
Definition at line 825 of file pointer_matrix.h.
|
inline |
Return whether the object is empty.
Definition at line 842 of file pointer_matrix.h.
|
inline |
Assign a new matrix pointer. Deletes the old pointer and releases its matrix.
Definition at line 833 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 851 of file pointer_matrix.h.

inlinevirtual |
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 863 of file pointer_matrix.h.

Matrix-vector product, adding to dst
.
The dimension of dst
is 1, while that of src
is the size of the vector representing this matrix.
