I was wondering if there is anyway to use a Q norm (i.e. sqrt(x’Qx) where Q is PSD) as an atom operation?

Otherwise I have to think/calculate by hand of the final norm structure, or decompose Q with eigen-decomposition.

`norm(chol(Q)*x)`

if Q is not singular, or more generally, `norm(sqrtm(Q)*x)`

, whether or not `Q`

is singular.
