Plotting Implicit Algebraic equations in MATLAB

Question

I wish to plot implicit functions in MATLAB. Like x^3 + xy + y^2 = 36 , equations which cannot be made into simple parametric form. Is there any simple method ?

Answer 1

There are two new functions to plot implicit function in R2016b:

fimplicit for f(x,y) = 0
fimplicit3 for f(x,y,z) = 0
