I'm trying to plot an iterated function system based on the Barnsley Fern. The fractal is started at point (0,0) and generates new points by using 4 transformations. I received several errors and an empty graph. Any suggestions on how to go around this. I'm new to MATLAB and thanks for any help.

function Modern_Art
A{1} = [1;2];
n = 100;
r = rand(100,1);
for i=1:100
if r(i)<0.01
A{i+1} = [0 0;0 0.16]*A{i};
elseif 0.01 <= r(i) && r(i) < 0.86
A{i+1} = [0.85 0.04;-0.04 0.85]*A{i} + [0;1.6];
elseif 0.86 <=r(i) && r(i) < 0.93
A{i+1} = [0.2 -0.26;0.23 0.22]*A{i} + [0;1.6];
elseif 0.93 <= r(i) && r(i) < 1
A{i+1} = [-0.15 0.28;0.26 0.24]*A{i} + [0;0.44];
end
end
A = cell2mat(A);
plot(A(1,:),A(2,:))
end
