[理工] [資結]-一些矩陣的計算問題
一、What is the address for a[5][3] for an array declared as a[7][8]?
Assume a row major ordering, 10 units of memory per element, and staring
address is 1000.
二、Given A as an N by N array(N>=2) with A[i,j]=0 if |i-j|>2. Then, determine
the maximal number of nonzero elements in A.
三、另外想請問一下row/column-major 到底怎麼判斷會比較準？
ex1: A(0,5)=36 A(1,4)=56 A(2,7)=92 是row-major嗎？
ex2: B(2,3)=18 B(3,2)=28 A(1,1)=2 是row-major嗎？
以上請賜教，感謝。
