format y axis on a graph

here is my code i need to format the y axis to go from 0 to 1 with increments of 0.1 im not sure how to go about doing this

x = linspace(0,2*pi);

y1 = sin(x);

y2 = abs(sin(2*x))/2;

plot(x,y1,x,y2)

[Wayne King]

    x = linspace(0,2*pi);
    y1 = sin(x);
    y2 = abs(sin(2*x))/2;
    plot(x,y1,x,y2)
    set(gca,'ylim',[0 1]);
    set(gca,'ytick',0:0.1:1);

But you're going to cut off your y1 because that assumes values less than 0.
