This is an example of how to create an line plot from a function in MATLAB®.
Read about the ezplot function in the MATLAB® documentation.
Go to MATLAB Plot Gallery
% Create the plot using the lemniscate function f(x,y) = (x^2 + y^2)^2 - x^2 + y^2 figure; ezplot('(x^2 + y^2)^2 - x^2 + y^2', [-1.1, 1.1], [-1.1, 1.1]); % Adjust the colormap to plot the function in blue colormap([0 0 1]); % Add a multi-line title title({'Lemniscate Function'; '(x^2 + y^2)^2 - x^2 + y^2'});
