thank you, but that i need single number rand

my listing math lab code

clc;clear;close all;

c=[10 2 20 11

12 7 9 20

4 14 16 18];

s=[15

25

10

];

d=[5 15 15 15];

[m,n]=size(c);

x=zeros(m,n);

phi=1:m*n

for i=1:m*n

k1 = randperm(length(phi))

ii=[1+mod((k1-1),m)]

j=[1+mod((k1-1),n)]

x(ii,j)=min(s(ii),d(j))

s(ii)= s(ii)-x(ii,j)

d(j)= d(j)-x(ii,j)

end

"Shuffle" the vector before you enter the loop. Inside the loop draw the next element of the vector that you haven't used yet.

r = randperm(52);
for k = 1:5
    fprintf("Drawing card %d.\n", r(k))
end
