I want to calculate a problem and graph it
I want to graph i and area but it only show one point on my graph
% question1
clear all
a = 1
vectori = []
areavec = []
figure;
for i = 0:20
a = a + a
area = a *(1/8).^i
scatter(i,area)
end

You must change this:
clear all
a = 1
vectori = []% ??
areavec = []
figure;
for i = 0:20
a = a + a
areavec(i+1) = a *(1/8).^i %area --> areavec and areavec is a vector, not a scalar
end
i = 0:20;
scatter(i,areavec) %area --> areavec and graph must be out of cycle
