class blaze::SVecScalarMultExpr< typename, typename, bool >
Expression object for sparse vector-scalar multiplications.
The SVecScalarMultExpr class represents the compile time expression for multiplications between a sparse vector and a scalar value.
template<typename , typename , bool >
Compilation switch for the selection of the subscript operator return type.
The returnExpr compile time constant expression is a compilation switch for the selection of the ReturnType. If the vector operand returns a temporary vector or matrix, returnExpr will be set to false and the subscript operator will return it's result by value. Otherwise returnExpr will be set to true and the subscript operator may return it's result as an expression.
template<typename , typename , bool >
Compilation switch for the serial evaluation strategy of the multiplication expression.
The useAssign compile time constant expression represents a compilation switch for the serial evaluation strategy of the multiplication expression. In case the sparse vector operand requires an intermediate evaluation, useAssign will be set to 1 and the multiplication expression will be evaluated via the assign function family. Otherwise useAssign will be set to 0 and the expression will be evaluated via the subscript operator.
template<typename , typename , bool >
Constructor for the SVecScalarMultExpr class.
- Parameters
-
vector | The left-hand side sparse vector of the multiplication expression. |
scalar | The right-hand side scalar of the multiplication expression. |
template<typename , typename , bool >

- Returns
- Iterator just past the last non-zero element of the sparse vector.
template<typename , typename , bool >
