[理工] 請問資結一題Row/Column major的問題

[iloveconic (樂陶陶)]

Assume in a byte machine. A is an array declared as
A[-1:m, 2:n] and each element occupied 3 bytes. The
address of A[3,5] ia at 180 and A[5,3] is at 138. Find
the address of the element A[-1,2]

我用Row major和Column major算出來的結果不一樣

想在此請問一下是怎麼判定是用Column major的@@

是因為A(3,5)=180
          V   V     這樣判定的嗎?
      A(5,3)=138


      A(3,5)=138
       ↑            那這樣就是Row major嗎?
      A(5,3)=180



麻煩各位了!!
