How to interchange/swap variable in matrix and store it to different variable.

 p = [90 90 -45 0 0 45 45 0 -45];
 p1 = p; %store temporary copy of p
 idx = [true diff(p)~=0];
 q = p(idx);
 idx = fliplr([true, diff(fliplr(p))~=0]);
 position_p = find(idx); pos = position_p;

I want to interchange positions of p according to position_p from right side. In every iteration only p(9) should be interchange.

p(9) interchange with p(8) //A/c to position_p right to left

 Layer(:,:,1) = [90 90 -45 0 0 45 45 -45 0];

p(9) interchange with p(7)

 Layer(:,:,2) = [90 90 -45 0 0 45 0 -45 45];

and so on...

position_p = [2 3 5 7 8 9] menas 1st interchange p(9) with p(8) then store layer and then interchange p(7) and so on....

ii = find(idx);
n = numel(ii);
out = zeros(n,numel(p));
out(1,:) = p;
i1 = fliplr(ii);
for jj = 2:n
    out(jj,:) = out(jj-1,:);
    out(jj,[i1(jj),end]) = out(jj,[end,i1(jj)]);
end

Lot of thanks Sir...

Can you reshape out to Layer(:,:,k) except 1st layer
