用matlab绘制Ackley函数的三维图形

function DrawAckley() %绘制Ackley函数图形 x=[-40:1:40]; y=x; [X,Y]=meshgrid(x,y); [row,col]=size(X); for l=1:col for h=1:row z(h,l)=Ackley([x(l),y(h)]); end end surf(X,Y,z); shading interp function result=Ackley(x) %Ackley 函数 [row,col]=size(x); if row>1 error('输入的参数错误'); end result=-20*exp(-0.02*sqrt((1/col)*(sum(x.^2))))-exp((1/col)*sum(cos(2*pi.*x)))+exp(1)+20;
