Hi. My function has to sort a numerical vector by using only while loops, diff(),any(), or all() Must Use a While Loop No For Loop n=length(v); while ~any(diff(v) >= 0) % detects if vector is sorted. i1=ceil(n*rand(1)); i2=ceil(n*rand(1)); temp=v(i1); v(i1)=v(i2); v(i2)=temp; end order = v;

Having vector sorted by using While Loops + Diff()

Hi. My function has to sort a numerical vector by using only while loops, diff(),any(), or all()

Must Use a While Loop
No For Loop

n=length(v);
while ~any(diff(v) >= 0) % detects if vector is sorted.
    i1=ceil(n*rand(1));
    i2=ceil(n*rand(1));
    temp=v(i1);
    v(i1)=v(i2);
    v(i2)=temp;
end
order = v;

That's better, but what question is being asked?

I see you edited what you posted, but you still have not asked a question. You made some statements, but you did not ask anything from us.

From my understanding of the question you want to write a function to sort vector using only while loops, diff(), any(), or all() but you are getting wrong outputs. There is error in your code in the condition part of while loop and to sort the vector in increasing order you should use the following code:

n=length(v); 
while any(diff(v) <= 0) % Change this line
    i1=ceil(n*rand(1)); 
    i2=ceil(n*rand(1)); 
    temp=v(i1); 
    v(i1)=v(i2); 
    v(i2)=temp; 
end 
order = v;
