Dears,

Currently I am working on some kind of randomizer where I generate white and black balls. In the first step I generate them on the graph as a horizontal "curve". In next step I generated similar "random curve", however, it is vertical curve and it starts only when in horizontal curve black ball appears:

Variable1 = 60;

Variable2 = 30;

% Arrays for the backbone

A = zeros(Variable1,2); %triol

B = zeros(Variable1,2); %dicarboxyacid

% Horizintal randomizer

for i=1:Variable1

if randi(100,1,1)<=Variable2

A(i,2)=1;

A(i,1)=i;

else

B(i,1)=i;

B(i,2)=1;

end

% Deletes all zeros in A

TestForZero = A(:,1) == 0;

A(TestForZero, :) = [];

% Vertical randomizer

for q = 1:height(A)

if randi(100,1,1) <= Variable2

C1(q,2) = q+1;

C1(q,1) = A(1,1);

else

C2(q,2) = q+1;

C2(q,1) = A(1,1);

end

for q = 1:height(A)

if randi(100,1,1) <= Variable2

D1(q,2) = q+1;

D1(q,1) = A(2,1);

else

D2(q,2) = q+1;

D2(q,1) = A(2,1);

end

% Visualization of the randomizer

hold on

plot(A(:,1),A(:,2),'o','MarkerFaceColor',"black",'MarkerEdgeColor',"black",'MarkerSize',10)

plot(B(:,1),B(:,2),'o','MarkerFaceColor',"white",'MarkerEdgeColor',"black",'MarkerSize',10)

plot(C1(:,1),C1(:,2:end),'o','MarkerFaceColor',"black",'MarkerEdgeColor',"black",'MarkerSize',10)

plot(C2(:,1),C2(:,2:end),'o','MarkerFaceColor',"white",'MarkerEdgeColor',"black",'MarkerSize',10)

plot(D1(:,1),D1(:,2:end),'o','MarkerFaceColor',"black",'MarkerEdgeColor',"black",'MarkerSize',10)

plot(D2(:,1),D2(:,2:end),'o','MarkerFaceColor',"white",'MarkerEdgeColor',"black",'MarkerSize',10)

axis off

hold off

As you can see, I managed to make vertical curves for more than one black ball in the horizontal curve. Nevertheless, I did it "manually". Is it possible to make it in some for loop?

The problem is I do not know how many of black balls will be created for each run. Moreover, in theory its amount is infinity, because by increasing Variable1 and Variable2 I increase the amount of black balls in the curves (in horizontal as well as vertical curves).

I thought about creating new arrays for each itteration, however, I found information that it is not preffered way and it can be done in other ways. Could you please help me with that?

Thank you in advance,

Cheers
