一种方法是使用surf。 [X,Y,Z]=peaks(50);figuresurf(X,Y,Z) 与所有图形对象一样,曲面具有可以查看和修改的属性。这些属性具有默认值。曲面对象的显示,s,显示最常用的曲面属性,例如EdgeColor,LineStyle,FaceColor,和FaceLighting。 s=surf(X,Y,Z) s=Surfacewithproperties:EdgeColor:[000]LineStyle:'-...

3 个别表面的透明度一个曲面的透明度是由它的AlphaData属性定义的。将alpha数据设置为标量值或值矩阵，指定曲面的每个顶点的透明度。FaceAlpha属性指示了如何通过顶点透明度来确定曲面的透明度。命令行键入：[X,Y,Z] = peaks(20);s2 = surf(X,Y,Z);s2.AlphaData = gradient(Z); % set vertex transparenciess2...
