Hello
How can i plot a 3d curve like (Figure 3D) as attached ?
For example:
x1 = [1 2 3 4 5 6 7 8 9 10];
x2 = [5 4 2 7 15 12 26 84 95 78];
x3 = [12 41 51 62 142 185 192 202 256 275 ];
plot3d (x1,x2,x3)
Using this program, I have obtained a line not a surface.
Please help me.

y3 = [0.30566 0.31675837 0.3280565163 0.4793385 0.98557455 3.04709 3.157375 3.269625 4.77027 9.7606137 29.5405784 30.576361 31.628 45.4737503 88.77938];
[Y1,Y2]= meshgrid (y1*1e-3 , y2) ; %(20:20:100,0:0.2:1);
figure (2)
surf(Y1,Y2,y3)
xlabel ('Length of layers (mm)')
ylabel('Load resistance (\Omega)')
zlabel('Power (\muW/g^2)')
