MATLAB: Find index of first nonempty cell in array

cell arrayempty cells

Hi,

I have a cell array with values and empty cells. I'd like to return the index of the first empty cell.

For example, for

 A = [pizza] [pepperoni] [cheese] [] []

I'd like to return a value of 4.

Thanks!

A = {['pizza'] ['pepperoni'] ['cheese'] [] []}
find(cellfun(@isempty,A),1)

x = {1,[],[],[]};
find(~cellfun(@isempty,x))

A = cell(size(A));
ii = ~cellfun('isempty',C);
A(ii) = cellfun(@(x)x(2),C(ii),'un',0);

or use loop for..end

A = cell(size(C));
for jj = 1:numel(C)
    if ~isempty(C{jj})
        A{jj} = C{jj}(2);
    end
end
