I would like to know how griddata operate. I would like to scatter 2D points to a 3D grid using the griddata interpolate. The code which brings some errors.
x=1:1:10;
y=11:1:20;
z= sqrt(x.^2+y.^2)
[xx,yy] = meshgrid(linspace(min(x),max(x),200),linspace(min(y),max(y),200))
zz=griddata(x,y,z,xx,yy,'nearest')
The error is as seen below.
Warning: The underlying triangulation is empty - the points may be collinear.
