Matlab画三维图的两种方法
2006-10-13 20:36
    这几天看到Ras函数（Rastrigin's Function），这个函数对模拟退火、进化计算等算法具有很强的欺骗性，因为它有非常多的局部最小值点和局部最大值点，很容易使算法陷入局部最优，而不能得到全局最优解。

    Ras函数为：


   Matlab的Help里面有这个函数的三维图像，但是没有解释是怎样画出来的。经过请教同学，得出两种方法，现记录在此。

第一：
[x,y]=meshgrid([0:0.1:4]);
z=20+x.*x+y.*y-10*(cos(2*pi*x)+cos(2*pi*y)); 
surfc(x,y,z)
shading interp

第二：
f=@(x,y) 20+x.*x+y.*y-10*(cos(2*pi*x)+cos(2*pi*y));
 ezsurf(f,[-2 2])
shading interp
