    %% Modify Implicit Plot After Creation
% Plot the implicit function $y\sin(x) + x\cos(y) - 1 = 0$ and assign the
% implicit function line object to the variable |fp|.

fp = fimplicit(@(x,y) y.*sin(x) + x.*cos(y) - 1)

%%
% Use |fp| to access and modify properties of the implicit function line
% object after it is created. For example, change the color, line style,
% and line width.
fp.Color = 'r';
fp.LineStyle = '--';
fp.LineWidth = 2;
