MATLAB stem3()用法及代碼示例

三維莖圖顯示從 xy-plane 延伸的線。 z-position 描述數據值的圓圈(默認)或其他標記符號終止每個詞幹。

用法

stem3(Z) // It plots the data sequence Z as stems that extend from the xy-plane.
stem3(X, Y, Z) // It plots the data sequence Z at the value specified by X and Y. X, Y, and Z must be all be vectors or matrices of the same size.
stem3(...,'fill')  // It specifies whether to color the interior of the circle at the end of the stem.
stem3(...,LineSpec) // It specifies the line style, marker symbol, and color for the stems.
h = stem3(...) // It returns handles to line graphics objects.

示例

創建一個三維莖圖來可視化兩個變量的函數。

x=t, y=tsin(t)
z=e^t/10-1
for 0â¤tâ¤6Ď
t=linspace(0,6*pi,200);
x=t; y=t.*sin(t);
z=exp(t/10)-1;
stem3(x, y, z,'filled')
