Hermitian and Involutory matrices not found in learning material

Hi KoAli,

Thank you for sharing your thoughts on how our Linear Algebra content could be improved. I will make sure to pass this feedback along to the appropriate team so we can discuss it. As we grow and expand, we’re continuing to add new content to offer a better education at Khan Academy. Investing more heavily in the content team is actually one of our major initiatives.

Warm regards,
