Detailed Description

template<typename, typename>
class blaze::TDVecTSMatMultExpr< typename, typename >

Expression object for transpose dense vector-transpose sparse matrix multiplications.

The TDVecTSMatMultExpr class represents the compile time expression for multiplications between transpose dense vectors and column-major sparse matrices.

Member Enumeration Documentation

template<typename , typename >
anonymous enum
private

Compilation switch for the evaluation strategy of the multiplication expression.

The useAssign compile time constant expression represents a compilation switch for the evaluation strategy of the multiplication expression. In case the sparse matrix expression requires an intermediate evaluation or the dense vector expression is a compound expression, useAssign will be set to true and the addition expression will be evaluated via the assign function family. Otherwise useAssign will be set to false and the expression will be evaluated via the subscript operator.
