阿新 • • 發佈：2018-12-20
1、cylinder函式：繪製三維圓柱圖
2、用法說明：
（1）[x,y,z]=cylinder 函式返回一半徑和高度都為1的圓柱體x，y，z軸的座標值，圓柱體沿其周長有20個等距分佈的點
（2）[x,y,z]=cylinder(r) 函式一個半徑為r、高度為1的圓柱體的x，y，z軸的座標值，圓柱體沿其周長有20個等距分佈的點
（3）[x,y,z]=cylinder(r,n) 函式一個半徑為r、高度為1的圓柱體的x，y，z軸的座標值，圓柱體沿其周長有n個等距分佈的點
（4）cylinder(...) 函式只繪製圓柱，沒有任何的輸出參量。其他參量及結果同上
