I have a matrix with several 5 layers. I want to plot the numbers at a specific gridpoint for layers 2,3, and 4. How would I go about doing this?
Thanks for the help!

x1=[2 3 4 5];
y1=[9 4 3 2];
x2=[11 20 30 50 ];
y2= [ 20 30 50 60];
plot(x1,y1)
hold on
plot(x2,y2)
hold off
This plot two line graphs on same plot
