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]}
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));
cisnan(your_cell)

There are many ways:
nanarray = cell2mat(cellfun(@isnan,A,'uni',0));
length(nanarray>0)
% the above gives you the answer -- for example
if (length(nanarray>0) > 0)
disp('The cell array contains NaNs')
end
