How to inverse all vectors in a struct

Hi, I have several structs with vectors in all of them. For some reason I have all vectors in wrong order. An example could be that they are 1 4 7 9 8 but I would like it to be 8 9 7 4 1. I wonder if there is a way to inverse all of the vectors inside a struct without having to call Structure.A, Structure.B etc as it would both be time consuming, line consuming and inconvenient!
I guess I am looking for something like fliplr(Structure) instead of fliplr(Structure.A)
All help is much appreciated! Fredrik

Structure= structfun(@fliplr, Structure, 'UniformOutput', false)

Compare the structfun approach with a loop:
f = fieldnames(S);
for k = 1:length(f)
af = f{k};
S.(af) = S.(af)(end:-1:1);
end
Inside structfun a loop is required also. Calling the function fliplr() has a certain overhead, so reverting the vectors locally is an advantage.
