swap values of an array

Hi! Every one

I have an array O = [11 12 13 21 14 22 23 31 25 24 32 33 34] ;

I want to swap a value with its adjacent value at two positions.The postions are defined by vector

v=[5 10]

I want output to be like

out = [11 12 13 21 22 14 23 31 25 32 24 33 34];

The number 14 is replaced by its adjacent 22 at postion 5.

Similarly,

The number 24 is replaced by its adjacent 32 in posioton 10.

Trivially done:

O = [11    12    13    21    14    22    23    31    25    24    32    33    34];
v = [5 10];

O([v;v+1]) = O([v+1;v]);  %v must be a row vector for this to work.

O([v v+1])=O([v+1 v]) % also this works

Hi Mazhar Ali,

Try this below:

for i = 1:numel(v)

    temp = O(v(i));
    replacemnt = O(v(i)+1);
    
    O(v(i)) = replacemnt;
    O(v(i)+1) = temp;

end
