%% Modify Implicit Plot After Creation % Plot $y \sin(x) +x \cos(y) = 1$. Specify an output to make |fimplicit| return % the plot object. syms x y eqn = y*sin(x) + x*cos(y) == 1; fi = fimplicit(eqn) %% % Change the plotted equation to $x \cos(y) + y \sin(x) = 0$ by using dot % notation to set properties. Similarly, change the line color to red and % line style to a dash-dot line. The horizontal and vertical lines in the % output are artifacts that should be ignored. fi.Function = x/cos(y) + y/sin(x) == 0; fi.Color = 'r'; fi.LineStyle = '-.';
