Suppose we have 2000 matrices and for each matrix we have a real value between [-3,3]. I want a plot the matrices along horizontal x-axis and their corresponding value on y-axis as shown in figure.

What the content of the arrays is is immaterial; what we don't know and you seemingly won't tell us, is anything about the source of these arrays--are they on disk, result of some calculation, a series of simulations, maybe based on the last comment...???
As IA says, "try SOMETHING and show us what isn't what you expect", don't make somebody trying to help you figure out what it is that you need help with or are trying to do...
You don't say what you want to do along this x-axis; and what happens to the x-axis values in each -- does it expand, do you have real time or just sample number, etc., etc., etc., ...

Try this:
for k = 1 : 2000
thisMatrix = GetMatrixSomehow(k);
y(k) = GetValueSomehow(thisMatrix);
end
plot(y, 'b-', 'LineWidth', 2);
grid on;
xlabel('Matrix Number', 'FontSize', 20);
ylabel('y', 'FontSize', 20);
