Detailed Description

Routines for symmetric rank-k updates, a specialized form of Matrix*Matrix multiplication.

Four possibilies for op, each with a different effect:

'N' -> C = beta*C + alpha*A*transpose(A) 'T' -> C = beta*C + alpha*transpose(A)*A 'H' -> C = beta*C + alpha*hermitian(A)*conjugate(A) 'C' -> C = beta*C + alpha*conjugate(A)*hermitian(A)
