我有一个单元阵列与南如图片所示. How can I convert NaN to string NaN meaning instead of of seeing NaN in the array, I want to see "NaN".

I have tried this: TC(cellfun(@(x) any(isnan(x)),TC,'UniformOutput',false)) = {"NaN"}; but no success.

Any help is appreciated.

                             A = NaN(2,5) ;
                            
                             C = arrayfun(@num2str,A,'UniformOutput',false)
                            
                                C =2×5 cell array
                               
                                {'NaN'} {'NaN'} {'NaN'} {'NaN'} {'NaN'} {'NaN'} {'NaN'} {'NaN'} {'NaN'} {'NaN'}

Try num2str

                             a = {nan 1 nan};
                            
                             cellfun (@num2str,a,'UniformOutput',0)
                            
                                ans =1×2 cell array
                               
                                {'NaN'} {'NaN'}

This didn't give me quite what I was looking for.

For clarification, TC is in the structure of:

TC = {[ "Mercury" , "Gemini" , "Apollo" ; ...

"Skylab" , "Skylab B" , "ISS" ], ...

[ "Mercury" , "Gemini" ;

"Skylab" , "Skylab B" ]}

% Output array

TC = cellfun(@(x) nan(size(x,1),1) ,TC, 'UniformOutput' ,false)

which created double NaN

However, I want it in string NaN, like this {'NaN'}

Hope this help.
