Given two arrays a and b how do you implement it to draw a graph with for loop such that the x axis is set of values from a and y axis is the values from b .i.e the graph is the format 'a' vs 'b........​..........​..........​..........​..........​.......'

for the above pic if B is arbitary (you can put any value) how do you use for loop to generate 2D plot

clear
t = 0:0.1:10;
for i = 1:length(t)
	B(i) = 2*t(i);
end
[x y] = find(B == max(B)) % finds the row and col indices where max value of B occurred 

figure(1)
plot(t,B)
axis([0 20 -1 30])
tt = 0:0.2:20;
for i = 1:length(tt)
	if tt(i) <= t(y) % use the index in time vector as condition 
		A(i) = 0;
	else 
		A(i) = 2;
	end
end
figure(2)
plot(tt,A)
axis([0 25 0 3])

 figure;
 plot(A,B); axis([-1 3 -1 30])
