Because the array sizes are fairly small here, the easiest thing might be to use my func2mat submission to express all your summations as matrix multiplications.
For example, a summation of a 4x1x12x12 array along its 3rd dimension can be represented by a matrix A obtained as follows,
z0=rand(4,1,12,12);
A=func2mat(@(z)sum(z,3) , z0);
To convince yourself of the equivalence, you can do
calc1=sum(z0,3);
calc2=A*z0(:);
>> norm(calc2(:)-calc1(:))
ans =
