Summation and array indexes

I am trying to write a function for an optimisation routine that requires the (total) summation of a matrix divided element by element by a second matrix, where the second matrix has a third dimension returning a vector the size of that third dimension.
i.e. something along the lines of a(1:n) = sum(sum(A./B(:,:,1:n))
which doesn't work. Any ideas?
Thanks

c = bsxfun( @rdivide, A, B );
a = squeeze( sum( sum( c ) ) );
should give the answer you want. Obviously you could do it in one line if you prefer.
