matlab quiver scale 在 Re: [問題] quiver畫完向量場、要怎麼標單位向量- 精華區MATLAB 的推薦與評價

標題Re: [問題] quiver畫完向量場、要怎麼標單位向量
時間Thu Nov 10 08:39:07 2005

※ 引述《kai25 (到處找網路)》之銘言：
: 我用quiver畫一個二為空間的向量場
: 給的參數是 x y 畫 u v 兩個向量的合成向量圖
: 畫完之後老闆希望還可以標上單位向量的長度
: → eatrol:help text 11/09 11:42
喔喔、關於這個
我昨天花了一整個晚上用google和help查了一個晚上
結果當然是沒有找到適合的才跑來這邊問啦..^^"

今天想了想沒找到可能是因為「不知道那個東西叫做什麼名字」
例如說他叫做「尺標」還是「單位向量」還是叫其他的名字
這個問題同樣發生在英文和指令上

另外呢
忽然想到如果我的x軸跟y軸的單位長度不一樣的時候
(x是1～64、y是2～32)
這個單位向量會因為角度的不同而「長度」看起來不同
這種情況我要怎麼標單位長度比較好呀..
請各位有經驗的前輩不吝指教嚕..^^| 謝謝！

推 Gwaewluin:help axis equal 11/10 09:16
推 semichina:使用quiver的時候,他會自動scale,如果可以自己控制scale 11/10 13:46
→ semichina:可以自己多增加一組單位向量的(x,y,u,v)在你想要的位置 11/10 13:46
→ semichina:也就是說在x和y矩陣最後新增一組你想標示單位向量的位置 11/10 13:49
→ semichina:,然後在u和v矩陣最後面新增單位向量,如此quiver後就OK 11/10 13:50
推 kai25:喔、這個意見不錯...謝啦...^^" 11/11 00:46
