Detailed Description

template<typename BasisFunctionType_, typename ResultType_>
class Bempp::IdentityOperator< BasisFunctionType_, ResultType_ >

Identity operator.

Let $X$ and $Y$ be two function spaces defined on the same grid. If $X \supset Y$ , an instance of IdentityOperator with domain $X$ and range $Y$ represents the orthogonal projection operator from $X$ to $Y$ . If $X \subset Y$ , it represents the inclusion operator from $X$ to $Y$ . In the special case of $X = Y$ , we have the standard identity operator. In BEM++ we (ab)use the term "identity operator" to refer to all these three cases.
