I don't want to use loop here.

A = rand(1,61) ;
idx = [(1:46)' (16:61)'] ; % get indices
iwant = mean(A(idx),2)

A = rand(180,270,61) ;
idx = [(1:46)' (16:61)'] ;
B = zeros(180,270,46,2) ;
B(:,:,:,1) = A(:,:,idx(:,1)) ;
B(:,:,:,2) = A(:,:,idx(:,2)) ;
Check and then use....confirm the result with a loop.
