Representation of directional cluster operators used to describe transformations of directional cluster bases.
Builds a dclusteroperator object matching a dcluster tree.
Constructs a directional cluster operator for a directional cluster and its descendants.
Row and column numbers will be set to zero.
- Parameters
-
- Returns
- dclusteroperator for
t
and its descendants.
Builds a dclusteroperator object matching a dclusterbasis object.
Constructs a directional cluster operator for a directional cluster basis and its descendants.
Row numbers will be set to zero, column numbers will be set to the ranks of the corresponding directional cluster basis.
- Parameters
-
- Returns
- dclusteroperator for
cb
and its descendants.
Delete a dclusteroperator object.
Releases the storage corresponding to the object.
- Parameters
-
Enumerates all directional cluster operators according to a directional cluster tree.
- Parameters
-
t | Directional cluster tree. |
co | Directional cluster operator belongs to t . |
- Returns
- Directional cluster operator containing numeration.

Initialize a dclusteroperator object.
Sets up the components of the object. If t
is not a leaf, the array son
is allocated, otherwise it is set to null.
- Parameters
-
co | dclusteroperator object to be initialized. |
t | Corresponding directional cluster. |
- Returns
- Initialized dclusteroperator object.
Initialize a dclusteroperator object for a leaf.
Sets up the components of the object. Sets son
to null. If t->sons>0
, this yields a partial directional cluster operator.
- Parameters
-
co | dclusteroperator object to be initialized. |
t | Corresponding directional cluster. |
- Returns
- Initialized dclusteroperator object.
Multiplies the matrices from one directional cluster operator with the corresponding matrices from another one.
For every cluster t
and direction the matrix from the dclusteroperator co2
will be multiplied by the corresponding matrix from the dclusteroperator co
and stored in co2
.
Obviously both dclusteroperator objects have to belong to the same directional cluster basis and the matrix sizes have to match.
- Parameters
-
co | Directional cluster operator, only used for the multiplication. |
co2 | Directional cluster operator, will be multiplied by the matrix from co and overwritten by the product. |
Create a new dclusteroperator object.
Allocates storage for the object and sets up its components.
- Parameters
-
t | corresponding directional cluster. |
- Returns
- Returns the new dclusteroperator object.
Creates a new dclusteroperator object for a leaf.
Allocates storage for the object and sets up its components.
- Parameters
-
t | Corresponding directional cluster. |
- Returns
- Returns the new dclusteroperator object.
Set a pointer to a dclusterbasis object, increase its reference counter, and decrease reference counter of original pointer target.
- Parameters
-
Change the number of rows and columns of a directional cluster operator and resize cb->C[i]
accordingly.
- Parameters
-
co | Directional cluster operator that will be changed. |
krow | New number of rows. |
kcol | New number of columns. |
i | Direction, which should be changed. |
Uninitializes a dclusteroperator object.
Invalidates pointers, freeing corresponding storage if appropriate, and prepares the object for deletion.
- Parameters
-
Reduce the reference counter of a dclusteroperator object.
If the reference counter reaches zero, the object is deleted.
- Parameters
-
