MATLAB: Problem with “Intersect” function

cell arraysintersectMATLAB

Hellow everyone! I have 2 cells.
A = '1,2,3';
B= '1,4,5,6';
But, When i try to use intersect function to get the common element(s) as my result, say
C = intersect(A, B);
I am getting an empty cell like this.
C =
Empty cell array: 1-by-0
Kindly help me, My result shall show like
C='1'
Your help will be highly appreciated!

But the shown code works:
A = '1,2,3';
B = '1,4,5,6';
C = intersect(A, B);
% C = ',1' % The commonly appearing characters ',' and '1'
According to the posted code, A and B are not cells, but char vectors, also called strings.
If you want to treat the numbers as numbers:
An = sscanf(A, '%g,');
Bn = sscanf(B, '%g,');
Cn = intersect(An, Bn)
% C = 1
If A and B are cells, use "A{1}" and "B{1}" instead.
It depends on your specific problem if the input data should be
A = {'1','2','3'};
or
A = [1,2,3]
Most likely you do not have to convert the cell string {'1,2,3'}, if you choose the rigth method to obtain the data at the beginning. Where do these data come from?
