How to unnest cell arrays using a for loop?

A = [{{{{4}}}}, {0}, {{1}}, {{{0}}}]

I need to unnest the cell array so I am left with just the numbers in a vector. [4 0 1 0]

I think you can use a for loop..

How do I do this?

A = [{{{{4}}}}, {0}, {{1}}, {{{0}}}]
B = zeros(size(A));
for iA = 1:numel(A)
    a = A{iA};
    while iscell(a)
        a = a{1};
    end
    B(iA) = a;
end

Or:

c = true;
while any(c)
    c    = cellfun('isclass', A, 'cell');
    A(c) = cellfun(@(x) x, A(c));
end
B = [A{:}]
