Detailed Description

Matrix transpose.

This header dispatches directly, because Armadillo and Blaze expose the operation under different names (arma::strans and blaze::trans). The overload accepts a generic expression type, so a caller can transpose an unevaluated backend expression as well as a materialised Matrix.

The result is the plain transpose, never the conjugate transpose. For the real matrices BELFEM uses almost everywhere the two coincide; for the complex Matrix<T> instantiations the LAPACK wrappers accept, trans does not conjugate.
