%% Specify Plotting Interval and Plot Piecewise Functions % Plot the piecewise function % % $$ \matrix{e^x & -3 < x < 0 \cr \cos(x) & 0 < x < 3.}$$ % % Plot multiple lines using |hold on|. Specify the plotting intervals using % the second input argument of |fplot|. Specify the color of the plotted % lines as blue using |'b'|. When you plot multiple lines in the same axes, % the axis limits adjust to incorporate all the data. fplot(@(x) exp(x),[-3 0],'b') hold on fplot(@(x) cos(x),[0 3],'b') hold off grid on
