I have two cell arrays of different sizes filled with chars. I want to loop through and find the indices of one cell where the char values are equal to each other.
for example,
cell1={'cat','dog','pig','cow','goat'}
cell2={'meow','cat','bark','goat'}
should return 1 and 5 if I loop through cell one.
If these were doubles, I would use
for i=1:size(cell1,2)
ind=find(cell2==cell1(1,i))
end
but with these variable types I'm having some trouble.
cell2{1,2}==cell1{1,1}
return the logcial True but
find(cell2==cell1{1,1})
returns the error message "Operator == is not supported for opperands type cell". I also tried using cellfun(@isequal, cell1, cell2) but I get an error message because the size and shape of my cells are not equal.
How can I get the desired result using these variable types?

To compare char arrays, strcmp() should be used. However, since you are using the lastest version of MATLAB, so there are easier ways
cell1={'cat','dog','pig','cow','goat'};
cell2={'meow','cat','bark','goat'};
idx = find(any(string(cell1) == string(cell2).'));
Result
>> idx
idx =
1 5
