Bubble sort not working like I want it

x = rand([12,1])

for j = 1:numel(x)-1;

      if x(j) > x(j+1);
          temp1 = x(j);
          x(j) = x(j+1);
          x(j+1) = temp1;
      end
  end

The script seems to recognize when an element is larger than the next, but it doesn't flip the elements. I don't understand why :S

Answer 1

[Benjamin]

A while loop that reset the iteration in case of a swap worked wonders!

[Azzi Abdelmalek]

You are just puting the greatest value at the end of your array. You should repeat the operation from 1 to n-1 then from 1 to n-2 and so on

Answer 2

[Honglei Chen]

This only gets the largest element to the bottom. You need another level of iteration to sort the rest of them.

Answer 3

[Azzi Abdelmalek]

x=[8 10 2 4 6] 
x(1)<x(2) % no action x(1)=8 , x(2)=10
x(2)>x(3) % x(2)=2; x(3)=10

at this step you have : 8,2,10, your array can't be sorted!
