Hi there,
If I want to plot a 3D surface with x,y,z variables, where x and y has diffrent length, then which function should I use? I saw most of plot require that x and y has same length.

And how would that plot be? If you wanted to plot it with pen and paper, how would you do it?

Ran in:
For a 3D plot (x,y) can have different lengths, if you are talking about pcolor, surf. HEre you are plotting a surface.
x = linspace(0,1,20) ;
y = linspace(0,1,30) ;
[X,Y] = meshgrid(x,y) ;
Z = sqrt(X.^2+Y.^2) ;
pcolor(X,Y,Z)
