HCL_BlockLinearOp_d( HCL_ProductVectorSpace_d * d, HCL_ProductVectorSpace_d * r )

Usual constructor; needs the domain and range spaces. The operators are defined with the SetNext method (by rows) or with the Set method.

HCL_BlockLinearOp_d( int r, int c )

Alternate constructor; only the arrangement of blocks (i.e. number of rows and columns) must be specified. The operators are defined with the Set method.

HCL_BlockLinearOp_d( HCL_LinearOp_d * A, HCL_LinearOp_d * B, HCL_LinearOp_d * C, HCL_LinearOp_d * D )

Provided for convenience in the special case of a 2x2 operator

HCL_BlockLinearOp_d( HCL_ProductVectorSpace_d * d, HCL_VectorSpace_d * r )

Special constructor for the case of a ``row'' operator

HCL_BlockLinearOp_d( HCL_VectorSpace_d * d, HCL_ProductVectorSpace_d * r )

Special constructor for the case of a ``column'' operator

int Initialized()

Initialized is a boolean method indicating whether the blocks in the operator have been initialized

int IsSet( int i, int j )

IsSet is a boolean indicated whether the (i,j) block has been initialized

virtual HCL_VectorSpace_d& Domain()

Domain space access.

virtual HCL_VectorSpace_d& Range()

Range space access.

HCL_LinearOp_d& operator)( int i, int j )

The () operator provides access to the individual operators.

int Rows()

Rows returns the number of rows in the array.

int Cols()

Cols returns the number of columns in the array.

Image methods

virtual void Image( const HCL_Vector_d & x, HCL_Vector_d & y )

Image computes the action of the operator on x, giving y.

void SetNext( HCL_LinearOp_d * L )

SetNext sets the next operator (by rows) to L

void Set( int i, int j, HCL_LinearOp_d * L )

Set sets the (i,j) block to L

I/O

virtual ostream& Write( ostream & str )

Write prints out the operators on the diagonal.
