How to change the elements's position of a vector by N consecutive times?

I want a loop that executes at one time only several combinations.

x = [1 2 3 4 5];

xp = randperm(numel(x), 2);

x(xp) = x(fliplr(xp))

>> test

x =

     1     2     4     3     5

>> test

x =

     1     3     2     4     5

Can't you simply use a for loop???

for k = 1 : N
    test
end

or you can use deal to do the swapping of indexes:

[x(xp(1)), x(xp(2))] = deal(x(xp(2)), x(xp(1)));
