%% Specify Plotting Interval and Plot Piecewise Contour Plot % Specify the plotting interval as the second argument of |fcontour|. When % you plot multiple inputs over different intervals in the same axes, the % axis limits adjust to display all the data. This behavior lets you plot % piecewise inputs. % % Plot the piecewise input % % $$ \matrix{{\rm erf}(x) + \cos(y) & -5 < x < 0 \cr \sin(x) + \cos(y) & 0 < x < 5}$$ % % over $-5 < y < 5$. fcontour(@(x,y) erf(x) + cos(y),[-5 0 -5 5]) hold on fcontour(@(x,y) sin(x) + cos(y),[0 5 -5 5]) hold off grid on
