Enumerations
enum class	uni20::linalg::blas::MatrixTransform : unsigned { uni20::linalg::blas::normal = 0U , uni20::linalg::blas::transpose = 1U , uni20::linalg::blas::conjugate = 2U , uni20::linalg::blas::conjugate_transpose = 3U }
	Logical matrix transform independent of a provider-specific opcode, although it happens to coincide with the OpenBLAS cblas ordering. More...

Functions
template<uni20::BlasScalar Scalar>
constexpr char	uni20::linalg::blas::blas_trans_char (MatrixTransform transform)
	Lower a transform to the BLAS transpose character spelling used by selected providers.
template<uni20::BlasScalar Scalar>
constexpr bool	uni20::linalg::blas::blas_trans_char_is_supported (MatrixTransform transform)
	Return whether the current baseline provider path accepts a transform directly.
template<uni20::BlasScalar Scalar>
constexpr MatrixTransform	uni20::linalg::blas::canonical_transform_for_scalar (MatrixTransform transform)
	Collapse conjugation-only distinctions for real scalar types.
constexpr MatrixTransform	uni20::linalg::blas::compose (MatrixTransform outer, MatrixTransform inner)
	Compose two matrix transforms as outer(inner(A)).
constexpr bool	uni20::linalg::blas::conjugates_values (MatrixTransform transform)
	Return whether a matrix transform applies element-wise conjugation.
constexpr bool	uni20::linalg::blas::swaps_axes (MatrixTransform transform)
	Return whether a matrix transform swaps the logical axes.
constexpr blas_int	uni20::linalg::blas::transformed_cols (blas_int rows, blas_int cols, MatrixTransform transform)
	Columns produced by applying transform to an untransformed matrix.
constexpr blas_int	uni20::linalg::blas::transformed_rows (blas_int rows, blas_int cols, MatrixTransform transform)
