 For real matrices, \c conjugate() is a no-operation, and so \c adjoint() is 100% equivalent to \c transpose().

 This is the so-called \ref TopicAliasing "aliasing issue". In "debug mode", i.e., when \ref TopicAssertions "assertions" have not been disabled, such common pitfalls are automatically detected.
