MATLAB: How to rename array layer number or iteration no.

Question

I have an array

 layer1 =
    90    90   -45     0     0    45    45     0   -45
    90    90   -45     0     0    45    45   -45     0
    90    90   -45     0     0    45     0   -45    45
    90    90   -45     0    45    45     0   -45     0
    90    90     0     0    45    45     0   -45   -45
    90   -45     0     0    45    45     0   -45    90
 layer = reshape(layer1(2:end,:)',1,size(layer1,2),(size(layer1,1)-1));

output

layer(:,:,1) =
    90    90   -45     0     0    45    45   -45     0
 layer(:,:,2) =
    90    90   -45     0     0    45     0   -45    45
 layer(:,:,3) =
    90    90   -45     0    45    45     0   -45     0
 layer(:,:,4) =
    90    90     0     0    45    45     0   -45   -45
 layer(:,:,5) =
    90   -45     0     0    45    45     0   -45    90

I'm calculating other values for layer1 and i want to reshape to layer(:,:,6) to layer(:,:,10)

 layer1 =
    90   -45     0     0    45    45     0   -45   90
    90   -45     0     0    45    45   -45     0   90
    90   -45     0     0    45     0   -45    45   90
    90   -45     0    45    45     0   -45     0   90
    90     0     0    45    45     0   -45   -45   90
   -45     0     0    45    45     0   -45    90   90

Сan it?

layer1 = circshift(layer1,[0 8]);

or

layer1 = layer1(:,[2:end,1]);

or

p = [90 90 -45 0 0 45 45 0 -45];
idx = fliplr([true, diff(fliplr(p))~=0]);
ii = find(idx);
n = numel(ii);
layer1 = zeros(n,numel(p));
layer1(1,:) = p([2:end,1]);
i1 = fliplr(ii);
for jj = 2:n
    layer1(jj,:) = layer1(jj-1,:);
    layer1(jj,[i1(jj)-1,end-1]) = layer1(jj,[end-1,i1(jj)-1]);
end
