ｎ
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.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
