i generate a sample for example it's size is 30. And i find its minimum.

for example sample is

A=[1 5 8 9 7 6 4 5] min(A)=1

and i want to delete 1 from A. new A is A=[5 8 9 7 6 4 5]

then i want to sampling 2 element for example b=[9 4]

and i want to delete this numbers from A. new A is A=[5 8 7 6 5]

then this continue when A has no elements.

how can i do this?

sayi= exprnd(100,1,30); enkucuk=min(sayi)

i dont do anything after these steps. Thank you

A=[1 5 8 9 7 6 4 5]   
[val,idx]=min(A)
A(idx)=[]
b=[9 4]
A(ismember(A,b))=[]

A=[1 5 8 9 7 6 4 5]   
b=nchoosek(A,2)
b=b(randi(size(b,1)),:)

%or

A=[1 5 8 9 7 6 4 5]  
k=2
idx=randperm(numel(A));
b=A(idx(1:k))
