如何用matlab绘制贝塞尔曲线
10阶贝塞尔曲线（平面曲线）
,控制点分别为
(0,1.2),(0.04,0.6),(0.15,0.51),(0.32,0.88),
(0.31,0.09),(0.52,0),(0.62,0.8),(0.89,0.87),(0.92,0.6),(0.92,0.3),
(0.75,0).

以下是运行结果：
程序代码：function bezier(x,y) x=[0,0.04,0.15,0.32,0.31,0.52,0.62,0.89,0.92,0.75]; y=[1.2,0.6,0.51,0.88,0.09,0,0.8,0.87,0.6,0.3,0];n=length(x);t=linspace(0,1);xx=0;yy=0;for k=0:n-1 tmp=nchoosek(n-1,k)*t.^k.*(1-t).^(n-1-k); xx=xx+tmp*x(k+1); yy=yy+tmp*y(k+1);endif nargout==2 X=xx;Y=yy;endh=plot(xx,yy);if nargout==1 X=h;
