How to reshape every cell in a structure

Hi,
I am trying to reshape every cell in a 1x4 structure with 10 fields. A simplified example would look like this but when I try to reshape every 1x48 cell into 4x12 cells I get the following error: Inputs to STRUCTFUN must be scalar structures.
b = struct('a', {[1:48], [1:48], [1:48], [1:48]})
structfun(@(a) reshape(a, 12, 4), b, 'UniformOutput', false)
Thoughts ?

arrayfun(@(x) reshape(b(x).a, 12, 4), 1:numel(b), 'UniformOutput', false)

Mmmm, something like this ?
b = struct('a', {[1:48], [1:48], [1:48], [1:48]})
fn = fieldnames(b);
for k = 1:length(fn)
j = char(fn(k))
b = arrayfun(@(x) reshape(b(x).j, 4, 12), 1:numel(b), 'UniformOutput', false)
end
fn = fieldnames(b);
for k = 1:numel(b)
for l = 1:numel(fn)
b(k).(fn{l})= reshape(b(k).(fn{l}), 4, 12);
end
end
Great, thank you.
