how to add element to a cell array struct without loop

Hi, I have a cell array, each of them is a structure, I want to add values in all arrays with field name myfield, how I do it without a loop?
for i = 1:10
C{i}.myfield = 1;
end
I can not use
C{1:10}.myfield = 1;
because it has the error:Expected one output from a curly brace or dot indexing expression, but there were 10 results. Maybe is there another simple method?
Thanks forward

This would be trivially easy if you had stored your data in a non-scalar structure (instead of inefficiently in lots of separate structures in a cell array):
>> [S(1:10).data] = deal(1)
S =
1x10 struct array with fields:
data
>> S(1).data
ans =
1
>> S(6).data
ans =
1

Unless there is a good reason why you need to keep the structures separate (e.g. different sizes or fields) I would simply convert to a non-scalar structure first, which would make all of your processing and code much simpler and more efficient. All you need is:
S = cell2mat(C)
You do not need to make your code ugly and inefficient because of someone else's bad data design.
PS: there is no way to access the structures in a cell array like that without a loop.
