class blaze::SMatScalarDivExpr< typename, typename, bool >
Expression object for sparse matrix-scalar divisions.
The SMatScalarMult class represents the compile time expression for divisions between a sparse matrix 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 matrix 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 evaluation strategy of the division expression.
The useAssign compile time constant expression represents a compilation switch for the evaluation strategy of the division expression. In case the given sparse matrix expression of type MT requires an intermediate evaluation, useAssign will be set to 1 and the division 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.
