how to create random marker indices in a loop?

I want to plot different marker indices , i have written the code in for loop and the plot function comes under the loop.So I need to create different marker for the plots in the same figure.

for i=2:6
    xxxx;
    YYYY;
    plot(x,y,'Marker','?')
    hold 
end

figure,hold on
x = 1:10;
all_marks = {'o','+','*','.','x','s','d','^','v','>','<','p','h'};
for i=1:6
y = rand(1,10);    
    plot(x,y,'LineStyle','none','Marker',all_marks{mod(i,13)})
end

This works well until i = 13 and then mod(13,13) is 0 :-)
