MATLAB创建一个三维曲面ax^2+y^2

Question

当a取1～10时的系列图连成的动画，求大神解答

Answer 1

x = linspace(-1,1,20);
y = linspace(-1,1,20);
[X,Y] = meshgrid(x,y);

figure
a = 1;
Z = a.*X.^2 + Y.^2;
h = surf(X,Y,Z);
zlim([0,15])

for a = 1:0.1:10
    Z = a.*X.^2 + Y.^2;
    set(h,'zdata',Z);
    drawnow
    pause(0.1)
end

直接上代码，复制到matlab中运行即可。
