class blaze::DMatTDMatSubExpr< MT1, MT2 >
Expression object for dense matrix-transpose dense matrix subtractions.
The DMatTDMatSubExpr class represents the compile time expression for subtractions between a row-major dense matrix and a column-major dense matrix.
template<typename MT1, typename MT2>
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 either 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 MT1, typename MT2>
Compilation switch for the serial evaluation strategy of the subtraction expression.
The useAssign compile time constant expression represents a compilation switch for the serial evaluation strategy of the subtraction expression. In case either of the two dense matrix operands requires an intermediate evaluation or the subscript operator can only return by value, useAssign will be set to 1 and the subtraction expression will be evaluated via the assign function family. Otherwise useAssign will be set to 0 and the expression will be evaluated via the function call operator.
