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
