equation (1): < x, y > = Σ xiyiwi
i=1
m n
equation (2): < A, B > = Σ Σ aijbij
i=1j=1
(其中i、j為下標。)
1 1 1 T
1.Use equation (1) with weight vector w = (-,-,-) to define an inner
4 2 4
3 T T
product for R and let x = (1,1,1) and y = (-5,1,3).
Show that x and y are orthogonal with respect to this inner product.
(請問respect在這裡的意思是?囧!)
m×n
2.Show that eqution (2) defines an inner product on R .
可以教我一下怎麼做嗎?
麻煩各位好心的大大了(鞠躬
