I want to put arrows on each of the lines parallel to x-axis using LOOP

Here I am able to put one arrow. Using

q = 0.2:.2:1;
    xx = [0.56 0.57];   % adjust length and location of arrow 
    yy = [q q];

I failed to get the desired arrows. How to modify the code below to get arrows on each blue lines.

p = 0.02:.07:1;
    plot([0; 1],[p; p], 'color','b');
    %q = 0.2:.2:1;
    xx = [0.56 0.57];   % adjust length and location of arrow 
    yy = [0.9 0.9];
    annotation('textarrow',xx,yy,'FontSize',13,'Linewidth',2)
    xlabel('$x\rightarrow$','FontSize',20,'interpreter','latex','FontWeight','normal','Color','k')
    ylabel('$y\rightarrow$','FontSize',20,'interpreter','latex','FontWeight','normal','Color','k')
     axis([0 1 0 .5]);
