%% Plot Implicit Symbolic Function % Plot the hyperbola described by the function $f(x,y) = % x^2 - y^2 - 1$ by first declaring the symbolic function |f(x,y)| using % |syms|. The |fimplicit| function uses the default interval of $[-5, 5]$ % for $x$ and $y$. syms f(x,y) f(x,y) = x^2 - y^2 - 1; fimplicit(f)
