plot(x,y1,'b',x,y2,'r') % Plot the two functions, the first in blue and the second in red
axis([-5 5 -1.2 1.2]) % Customize the axis with x=[-5 5] and y=[-1.2 1.2]
grid % Turn on the grid
title('Our tanh plot') % Put a title on the plot
xlabel('x') % Label the x-axis
ylabel('tanh(x)') % Label the y-axis
