计算表达式 的梯度并绘图。
正确答案:
>> v = -2:0.2:2;
>> [x,y] = meshgrid(v);
>> z=10*(x.^3-y.^5).*exp(-x.^2-y.^2);
>> [px,py] = gradient(z,.2,.2);
>> contour(x,y,z)
>> hold on
>> quiver(x,y,px,py)
>> hold off
>> [x,y] = meshgrid(v);
>> z=10*(x.^3-y.^5).*exp(-x.^2-y.^2);

>> contour(x,y,z)
>> hold on
>> quiver(x,y,px,py)
>> hold off
