Plotting Multivariable function poltting

How can plot f(x,y)= xy/(x^2+y^2) if (x,y) ≠ (0,0) and 0 if (x,y)=(0,0)

Answer 1

[Ege Keskin]

[X,Y] = meshgrid(1:.2:10);                                
Z =(X*Y) / (X^2 + Y^2);
surf(X,Y,Z)

You should avoid including 0 within the grid boundary since it creates a singularity.

Answer 2

[Dirk Herschberger]

[X,Y] = meshgrid(1:.2:10);

Z =(X*Y) / (X^2 + Y^2);

surf(X,Y,Z)

Answer 3

[MORAM]

[X,Y] = meshgrid(1:.2:10);

Z =(X*Y) / (X^2 + Y^2);

surf(X,Y,Z)
