MATLAB: How to cut and add values from every iteration. Please Help

Question

 p = [90 90 -45 0 0 45 45 0 -45];  p1 = p; %store temporary copy of p
p_descend = sort(p, 'descend');
p_ascend = sort(p,'ascend');
idx = [true diff(p)~=0];
q = p(idx); q1=q; %temporary copy of q
idx = fliplr([true, diff(fliplr(p))~=0]);
position_p = find(idx); pos = position_p;
ii = find(idx);
n = numel(ii);
layer1 = zeros(n,numel(p));
layer1(1,:) = p;
i1 = fliplr(ii);
for j = 2:n
    layer1(j,:) = layer1(j-1,:);
    layer1(j,[i1(j),end]) = layer1(j,[end,i1(j)]);
end
layer = reshape(layer1(2:end,:)',1,size(layer1,2),(size(layer1,1)-1));

I want to store last value of layer

means values should be

 out(:,:,1) = [0];%add last value from every iteration
 out(:,:,2) = [0 45];%last value of iteration 1 & 2
 out(:,:,3) = [0 45 0];
 out(:,:,4) = [0 45 0 -45];
 out(:,:,5) = [0 45 0 -45 90];

and i need last values from every iterations

Hi Ranjan! Edited loop for..end in your code.

output1 = cell(n-1,1);
for jj = 2:n
    layer1(jj,:) = layer1(jj-1,:);
    layer1(jj,[i1(jj),end]) = layer1(jj,[end,i1(jj)]);
    output1{jj-1} = layer1(jj,(end-jj+2):end);
end
