Forwarding.h File Reference

How a function that stores a matrix argument takes it (decisions.md [forwarded-matrices]): the concept MatrixExpression, which constrains its forwarding reference so that an rvalue is moved, and internal::castScalar(), which forwards a matrix that already has the scalar rather than copying it; and internal::forwardLike(), std::forward_like for every standard library.

Concepts
concept	Emrys::MatrixExpression
	A dense matrix or matrix expression, possibly cv- or reference-qualified: what a const Eigen::MatrixBase<Derived>& parameter accepts.
concept	Emrys::DiagonalExpression
	A diagonal matrix or diagonal expression, possibly cv- or reference-qualified, such as v.asDiagonal() or an Eigen::DiagonalMatrix: what a const Eigen::DiagonalBase<Derived>& parameter accepts.
concept	Emrys::CovarianceExpression
	A covariance as a function that stores one takes it: a MatrixExpression, or a DiagonalExpression, whose diagonal holds the variances and whose other entries are zero, so that GaussianParams<State>{mean, variances.asDiagonal()} needs no toDenseMatrix().

Detailed Description

How a function that stores a matrix argument takes it (decisions.md [forwarded-matrices]): the concept MatrixExpression, which constrains its forwarding reference so that an rvalue is moved, and internal::castScalar(), which forwards a matrix that already has the scalar rather than copying it; and internal::forwardLike(), std::forward_like for every standard library.
