真心求教labview的三维曲面拟合问题，希望高手能出手相助！

求见高手出现~非常感谢

有人做过类似的研究吗？

这属于二元高阶多项式的拟合

有没有高手出现？

高手在哪儿啊~~

这个问题这么艰难吗？没有人愿意试试？

永不放弃，继续求教

继续求教，非常感谢支持

>我*，看着就好高大上啊，高数，微积分方面在下是小白，帮不了，看看  帮顶一下吧

非常感谢，继续求教

高手请出现，快来快啦

你研究下这个代码!

x = rand(1,10);
y = rand(1,10);
z = (3-2*x-5*y)/4; % Equation of the plane containing
% (x,y,z) points is 2*x+5*y+4*z=3
Xcolv = x(:); % Make X a column vector
Ycolv = y(:); % Make Y a column vector
Zcolv = z(:); % Make Z a column vector
Const = ones(size(Xcolv)); % Vector of ones for constant term
Coefficients = [Xcolv Ycolv Const]Zcolv; % Find the coefficients
XCoeff = Coefficients(1); % X coefficient
YCoeff = Coefficients(2); % X coefficient
CCoeff = Coefficients(3); % constant term
% Using the above variables, z = XCoeff * x + YCoeff * y + CCoeff
L=plot3(x,y,z,'ro'); % Plot the original data points
set(L,'Markersize',2*get(L,'Markersize')) % Making the circle markers larger
% set(L,'Markerfacecolor','r') % Filling in the markers
hold on
[xx, yy]=meshgrid(0:0.1:1,0:0.1:1); % Generating a regular grid for plotting
zz = XCoeff * xx + YCoeff * yy + CCoeff;
surf(xx,yy,zz) % Plotting the surface
title(sprintf('Plotting plane z=(%f)*x+(%f)*y+(%f)',XCoeff, YCoeff, CCoeff))
% By rotating the surface, you can see that the points lie on the plane
% Also, if you multiply both sides of the equation in the title by 4,
% you get the equation in the comment on the third line of this example

请问楼主解决了没有，有的话能分享一下吗，万分感谢

LV自带例程有一个三维曲线拟合是用的Matlat节点
自己搜一下
