I have a 13x5 cell array which contains 4 'NaN' and I need to convert them from 'NaN'(string) to NaN(numeric). I have to use a nested loop as well the strcmp function but I don't know where to start.

Is this?
>> str2num('NaN')
ans =
NaN
Or
data={2,5,NaN,6}
cell2mat(data)
#
data =
1×4 cell array
{[2]} {[5]} {[NaN]} {[6]}
ans =
2 5 NaN 6

I tried both them earlier but it doesn't accept either of them. I provided a comment below to be concise. It wanted me to use the compare string function (strcmp) and a nested loop.
%Change the 'NaN' in the materialsData cell array to NaN using a nested
%loop. strcmp(s1,'NaN')can be used to find if s1 is 'NaN'.
