Detailed Description
template<class F = concepts::Real>
class bem::D_1< F >
Diagonal scaling operator for the piecewise constant basis.
The scaling factor is one over the square root of the support size. This is the inverse operator of bem::D.

◆ operator()() [4/5]
|
virtualinherited |
Application operator for complex function fncY.
Computes fncX = A(fncY) where A is this operator. fncX becomes complex.
In derived classes its enough to implement the operator() for complex Operator's. If a real counterpart is not implemented, the function fncY is splitted into real and imaginary part and the application operator for real functions is called for each. Then the result is combined.
If in a derived class the operator() for complex Operator's is not implemented, a exception is thrown from here.
◆ operator()() [5/5]
|
virtualinherited |
Application operator for real function fncY.
Computes fncX = A(fncY) where A is this operator.
fncX becomes the type of the operator, for real data it becomes real, for complex data it becomes complex.
In derived classes its enough to implement the operator() for real Operator's. If a complex counterpart is not implemented, the function fncY is transformed to a complex function and then the application operator for complex functions is called.
If in a derived class the operator() for real Operator's is not implemented, a exception is thrown from here.
