Matlab或python如何做出如图二元函数的surface plot？

Question

用matlab或python作出，求和和求积分部分怎么做到surf(x,y,z)里去哪？

Answer 1

这个好做啊

f = @(y)0:y-1;
zfun = @(x, y) x*5*y + 5*x*y+x*sum(5/3*f(y).^3) ;
x = 1:1:20;
y = 1:1:20;
[X,Y] = meshgrid(x,y);
Z  = zeros(size(X));
for i = 1:numel(X)
Z(i) = zfun(X(i), Y(i));
end
surf(X,Y,Z)
xlabel('X')
ylabel('Y')
zlabel('Z')

有帮助望采纳哟，谢谢啦
