Matrix moving mean with overflow average

I am wondering if there is a (simply) way when using movmean for controlling row overflow and for specifying a rectangular window instead of a square window. The idea would be to keep averaging the patch corresponding to each number in red until the end of row is found, and simply jump to the next row. Thanks!

Here's one way. I assumed here you want the same wrap-around to occur in the lower-right corner of the matrix as well.
A=reshape(1:24,[],4)'
B=[A,circshift(A(:,1:2),-1) ]
slidingMeans=conv2(B,ones(3)/9,'valid')

win = [3 5]; % rows, cols
A=reshape(1:24,[],4)'
B=[A,circshift(A(:,1:win(2)-1),-1)];
B(end,end-win(2)+2:end)=nan
slidingMeans=conv2(B,ones(win)/prod(win),'valid' )
