http://pastebin.com/B2m2VPrs I have this data. I want to made a surface which will represent this data. Any idea how to do it : ? I tried a bit, but i feel green in making 3dplots in matlab.

If you have the Curve Fitting Toolbox,

doc sfit
doc sftool

 hi,  try :

 plot3(X,Y,Z)
sqrt(120)
X(end+1)=X(end);
Y(end+1)=Y(end);
Z(end+1)=Z(end);
X=reshape(X,11,11);
Y=reshape(Y,11,11);
Z=reshape(Z,11,11);
figure,surf(X,Y,Z); % OR
figure, mesh(X,Y,Z)

Answer 3

Thanks for your help, it looks quite good, so this is enough for me .

more resolution : %2nd part

 X=interp2(X,2);
 Y=interp2(Y,2);
 Z=interp2(Z,2);
 surf(X,Y,Z)

Answer 4

[ethan josue]

plot3(X,Y,Z)

sqrt(120)

X(end+1)=X(end);

Y(end+1)=Y(end);

Z(end+1)=Z(end);

X=reshape(X,11,11);

Y=reshape(Y,11,11);

Z=reshape(Z,11,11);

figure,surf(X,Y,Z); % OR

figure, mesh(X,Y,Z)
