structure containing empty string arrays

Hi, I'm using a structure to hold some text data. The fields of the structure are initialised as cells. However it seems that if the field is left empty then the value is converted to a double meaning I can't consistently index that value. Do I need to specifically test each value or is there a better way? Thanks
x=struct('a',{},'b',{});
x(1).a={'abc' 'bbc'};
x(1).b={'cbc'};
x(2).a={'dbc'};
for iloc=1:2
sprintf('%s,%s\n',...
x(iloc).a{:},...
x(iloc).b{:})
end

You can use
x=struct('a',{''},'b',{''});
Edit
n=10;
v=arrayfun(@(x) {''},1:n,'un',0)
a=struct('a',v,'b',v)

Ok, use this, it should work
n=10;
v=arrayfun(@(x) {''},1:n,'un',0)
a=struct('a',v,'b',v)

You should be able to use repmat() to create a cell array of empty strings:
C = repmat({''},10,10)
And then feed this into the struct() constructor.

@Tom, works fine for me:
C = repmat({''},10,10)
S = struct('C',C)
S(10,1).C = 'pi'
