f(x,y)=(x^2+y^2)/x = 0

How do I plot this function on 3D graph?

Thank you

doc fimplicit

thank you

[Nguyen Phuoc]

but fimplicit just plot in 2D graph

[madhan ravi]

doc fimplicit3

[Nguyen Phuoc]

fimplicit3 use to graph f(x,y,z)=0 in 3D but I have to draw f(x,y)=0 in 3D

@Nguyen Phuoc use fsurf function or mesh function

% simple way 
f = @(x,y) (x.^2 + y.^2)./x;
fsurf(f,[0,1])

%  2 
x = linspace(0,1,100);
y = linspace(0,1,100);
[X,Y] = meshgrid(x,y);
mesh(X,Y,(X.^2+Y.^2)./X) % use a mesh 
view([30,10])
