MATLAB: Does a cell vector contains only NaN

nan

 Dear all,
I have
A={
 [NaN]
    [NaN]
    [NaN]
    [NaN]
    [NaN]
    [NaN]
    [NaN]
    [NaN]
    [NaN]
    [NaN]
    [NaN]
    [NaN]
    [NaN]
    [NaN]
    [NaN]
    [NaN]
    [NaN]
    [NaN]
    [NaN]
    [NaN]
    [NaN]
    [NaN]
    [NaN]
    [NaN]
    [NaN]
    [NaN]
    [NaN]
    [NaN]
    [NaN]
    [NaN]
    [NaN]
    [NaN]
    [NaN]
    [NaN]
    [NaN]
    [NaN]
    [NaN]
    [NaN]}
and I want to find a command that will tell me if A contains only NaN.
I tried
 all(isnan(cell2mat(A))), 2)  == NaN
but it does not work
cheers

cisnan = @(C)all(cellfun(@(x)all(isnan(x(:))),C));
