Hi! I don't understand because my code gives an error
if (prefixTree(1,4).prefixTree2(:,2)=='2')
unique(prefixTree(1,4).prefixTree2(:,3))
end
Error:
Undefined function 'eq' for input arguments of type 'cell'.
Thanks

Relational operators can be used with numeric arrays or character arrays. It makes no sense to use them with cell arrays. Consider the following:
>> {3}==3 % cell array
Undefined function 'eq' for input arguments of type 'cell'.
>> 3==3 % numeric array
ans =
1
>> strcmp('3','3')
ans =
1
>> strcmp({'3'},'3')
ans =
1
Here some of the other questions asked by people trying to perform numeric operations on cell arrays (which is always an error, as numeric operations can only be performed on numeric arrays):
