用matlab画三维散点曲面图

Question

各位好！请问我现在有一个txt文件夹里面有六列，我想把前三列用曲面图来拟合，应该怎样画呢？祝愿各位事事顺心！

建议用scatteredInterpolant函数

f = scatteredInterpolant(x,y,z);
[X,Y] = meshgrid(linspace(min(x),max(x)), linspace(min(y),max(y)));
Z=zeros(size(X));
Z(:) = f(X(:),Y(:));
scatter3(x,y,z,10,'r','filled'); hold on
mesh(X,Y,Z)
legend('原来散点', '拟合曲面')

有帮助望采纳哟谢谢啦
