Why is it easy? From the point of view of a mathematician perhaps. I
just experimented towards the desired result.
ishermitian ((]+[*~:) +@|:) A

This is an easy one. A Hermitian matrix matches its conjugate transpose.
Write a verb hft that creates a Hermitian matrix from a triangular one that has
a real diagonal.
