daily data into weekly mean for whole year

I have 3D matrix 100x150x365 (Column 3 shows number of days). I want to get weekly mean in loop with same first two dimensions. At the end I need 100x150x53 (53 weeks). Please share your experience to solve this problem.

Let A - your array

[m,n,k] = size(A);
p = 7;

i3 = ceil((1:k)'/p);
[ii,jj,kk] = ndgrid(1:m,1:n,i3);
out = accumarray([ii(:),jj(:),kk(:)],A(:),[],@mean);

Thank you for quick response, your answer in right in your own way but I want week-wise mean data. like 100x150x1 (First week), 100x150x1 (second week). simply i need week-wise separately data.. is it possible?

in my case: first week -> out(:,:,1); second week -> out(:,:,2) and etc.
