5F推aramilcat:X = [];06/02 17:58
6F→aramilcat:for i = [1:5;6:10]06/02 17:59
7F→aramilcat: X = [ X sum(i)];06/02 17:59
8F→aramilcat:end06/02 17:59
9F→aramilcat:diag(X)06/02 17:59
10F→aramilcat:我這樣寫會不會很多餘...QQ 我也剛初學06/02 18:01
11F推aramilcat:X = zeros(5)06/02 18:31
12F→aramilcat:for i = [1:5;6:10]06/02 18:31
13F→aramilcat: X(i(1),i(1)) = i(1) + i(2)06/02 18:32
14F→aramilcat:end06/02 18:32
15F→aramilcat:恩...這樣寫比較接近原po想要問的感覺？06/02 18:32
16F推aramilcat:因為for迴圈是依序取用變數的行向量，所以寫成矩陣形式06/02 19:12
17F→aramilcat:就可以做到你想要做的東西06/02 19:12
