The conjugation of complex matrices is a special case of a more general construction which could be considered: for any field F with an automorphism phi one might want to apply phi to vectors and matrices over F "coordinatewise". I don't know if SAGE yet has anything like field automorphisms in it (I looked in the Category part of the reference manual but could not see it) but I can easily imagine other situations where this concept might be useful (think of Galois groups, or --special case really-- Frobenius automorphisms of finite fields.
Having done that then it would still be a good idea to have the Hermitian conjugate-transpose defined specifically for complex vectors and matrices. John -- Prof. J. E.
