- Rooibos is actually pronounced
Pico de gallotranslates to
rooster's beak-- a little peck of flavor.
- For complex symmetric M, K, the expression (vT K v) / (vT M v) is more accurate than the standard Rayleigh quotient for estimating an eigenvalue from an approximate eigenvector v, assuming vT M v is nonzero.
So now you know.
