f(x,y) = (x+y+xy+1) / xy = 0
Hi, How can I plot 2D of the function above on MUPAD or Note ? It is simple 2D x, y space but I couldn't figure it out.
You can do that with the Symbolic Math Toolbox and the fcontour function, setting ‘LevelList’ to a vector of zeros:
syms x y f(x,y) = (x+y+x*y+1) / (x*y);
figure(1) fc = fcontour(f); fc.LevelList = [0 0];
See the documentation on fcontour for details.
