Making a world cup tournament simulator

I am making a world cup simulator

I am done with making the group stage simulator

How do I write a code for the tournament stage?

for example, the first place from group A is playing against the second place from group B. The second place from group A is playing against the first place from group B.

A={'Qatar';'Ecuador';'Senegal';'Netherlands'};
teamRank = randperm(4);
A_advance = A(teamRank(1:2))

B={'England';'IR Iran';'USA';'Euro Play-off'};
teamRank = randperm(4);
B_advance = B(teamRank(1:2))

C={'Argentina';'Saudi Arabia';'Mexico';'Poland'};
teamRank = randperm(4);
C_advance = C(teamRank(1:2))

D={'France';'IC Play-off 1';'Denmark';'Tuinisa'};
teamRank = randperm(4);
D_advance = D(teamRank(1:2))

E={'Spain';'IC Play-off 2';'Germany';'Japan'};
teamRank = randperm(4);
E_advance = E(teamRank(1:2))

F={'Belgium';'Canada';'Morocco';'Coratia'};
teamRank = randperm(4);
F_advance = F(teamRank(1:2))

G={'Brazil';'Serbia';'Switzerland';'Cameroon'};
teamRank = randperm(4);
G_advance = G(teamRank(1:2))

H={'Portugal';'Ghana';'Uruguay';'Korea Republic'};
teamRank = randperm(4);
H_advance = H(teamRank(1:2))

these are my codes for the group stage

Hi Er Le,

I understand that you would like to create a World Cup tournament simulator. I see that you have already written the code for the group stage simulator. To simulate the tournament stage, you can first define the Round of 16 matchups based on the rules you have specified and then simulate the matches, assuming the results are random.

Here is an example code to do so:

A={'Qatar';'Ecuador';'Senegal';'Netherlands'};
teamRank = randperm(4);
A_advance = A(teamRank(1:2));
B={'England';'IR Iran';'USA';'Euro Play-off'};
teamRank = randperm(4);
B_advance = B(teamRank(1:2));
C={'Argentina';'Saudi Arabia';'Mexico';'Poland'};
teamRank = randperm(4);
C_advance = C(teamRank(1:2));
D={'France';'IC Play-off 1';'Denmark';'Tuinisa'};
teamRank = randperm(4);
D_advance = D(teamRank(1:2));
E={'Spain';'IC Play-off 2';'Germany';'Japan'};
teamRank = randperm(4);
E_advance = E(teamRank(1:2));
F={'Belgium';'Canada';'Morocco';'Coratia'};
teamRank = randperm(4);
F_advance = F(teamRank(1:2));
G={'Brazil';'Serbia';'Switzerland';'Cameroon'};
teamRank = randperm(4);
G_advance = G(teamRank(1:2));
H={'Portugal';'Ghana';'Uruguay';'Korea Republic'};
teamRank = randperm(4);
H_advance = H(teamRank(1:2));

% Define the Round of 16 matchups
roundOf16 = {
    A_advance{1}, B_advance{2};
    A_advance{2}, B_advance{1};
    C_advance{1}, D_advance{2};
    C_advance{2}, D_advance{1};
    E_advance{1}, F_advance{2};
    E_advance{2}, F_advance{1};
    G_advance{1}, H_advance{2};
    G_advance{2}, H_advance{1};
};

% Function to simulate a match
simulateMatch = @(team1, team2) team1{randi(2)};

% Simulate the Round of 16
quarterFinals = cell(8, 1);
for i = 1:8
    quarterFinals{i} = simulateMatch(roundOf16(i, :));
end

% Define the Quarter Finals matchups
quarterFinalMatchups = reshape(quarterFinals, 2, 4)';

% Simulate the Quarter Finals
semiFinals = cell(4, 1);
for i = 1:4
    semiFinals{i} = simulateMatch(quarterFinalMatchups(i, :));
end

% Define the Semi Finals matchups
semiFinalMatchups = reshape(semiFinals, 2, 2)';

% Simulate the Semi Finals
finals = cell(2, 1);
for i = 1:2
    finals{i} = simulateMatch(semiFinalMatchups(i, :));
end

% Simulate the Final
champion = simulateMatch(finals);

% Display the results
disp('Champion:');

Champion:

disp(champion);
