How to stop a rand function from getting the same result in a for loop

Hey guys basic question.

I have this code here and i want to print the card deck in a random order:

for x = 1:52
y = randi([1 52]);
    if y == 1
        fprintf('%s\n','Spade Ace')
    elseif y == 2
        fprintf('%s\n','Spade 2')
(continues through the whole card deck 1-52)
    elseif y == 51
        fprintf('%s\n','Clubs Queen')
    else
        fprintf('%s\n','Clubs King')
    end
end 

Is there a way I can stop the rand function from comming up with the same number?

Answer 1

[Walter Roberson]

cards = {'Spade Ace', 'Spade 2', 'Spade 3'    up to  'Clubs Queen', 'Clubs King'};
x = randperm(52);
fprintf('%s\n', cards{x});

No loop needed. rand() not explicitly used (it is used inside of randperm)

Got it sir

I dont know how to stop rand function from comming up with same number but there is a way you can do that by indexing and removing numbers.

z = 1:52;
x = zeros(1,52);
for i =1:52
    y = randi([1 length(z)]);% 
    x(i) = z(y);
    z(y) = [];
end

This will generate random number without repeating them

I stored all the values in x, to check if they are right type following in command window

sort(x)

it will be from 1:52 without any repeatition
