How to make a loop that will find common elements between many arrays of strings, and omit the arrays that have already been compared?

I have many arrays of the same length of 100 string values. I need to compare each array with each subsequent array, have the similar values printed, and then have the same comparison done with all the other arrays. This is what I have so far:

T = Table

T{:,:}; % creates array from table T

A= table2array(T(1,:));

B= table2array(T(2,:));

C= table2array(T(3,:));

D= table2array(T(4,:));

E= table2array(T(5,:));

F= table2array(T(6,:));

G= table2array(T(7,:)); % sets each row to individual array

I = intersect(A,B) % intersection between 2 arrays (rows)

Hi Gemma,

The following code helps in converting the table to array of M*N with each row corresponding to the table row

A = table2array(T);      %%T is a table, and A is an array where each row corresponds to each row in table
sizeOfArray = size(A);   %% sizeOfArray holds the size of the array A

The following code helps in the looping of the array row wise and finding the similar strings

for i = 1:sizeOfArray(1)           %% i runs from 1 to last row
    for j = i+1:sizeOfArray(1)     %% j runs from i+1 to last row
        common = intersect(A(i,:),A(j,:));
        disp("Comparing array "+i+" and array "+j)
        if numel(common)==0
            disp("No Matching elements")
        else
            disp(common)
        end
    end
end

Refer to this documentation numel for more information on numel.
