Thread Subject: combinations of N matrixes taken K at a time

Hey I’m a new user.
I want to perform this:

I have 6 square matrixes A B C D E F
I want to find the possible combinations of these matrixes taken 3 at a time and calculate the product of the determiner of each combination
In order to find all possible combinations I can do this:
MAT={‘A’,’B’,’C’,’D’,’E’,’F’}
comb=nchoosek(MAT,3)
The results is:

comb =

    'A' 'B' 'C'
    'A' 'B' 'D'
    'A' 'B' 'E'
    'A' 'B' 'F'
    'A' 'C' 'D'
    'A' 'C' 'E'
    'A' 'C' 'F'
    'A' 'D' 'E'
    'A' 'D' 'F'
    'A' 'E' 'F'
    'B' 'C' 'D'
    'B' 'C' 'E'
    'B' 'C' 'F'
    'B' 'D' 'E'
    'B' 'D' 'F'
    'B' 'E' 'F'
    'C' 'D' 'E'
    'C' 'D' 'F'
    'C' 'E' 'F'
    'D' 'E' 'F'
Then I know all combinations

Now I want to create with a for cycle a matrix with like this:

Det=[|A|*|B|*|C| , | A|*|B|*D|,………]
How can I perform this multiplication?
The problem is that in the matrix comb, A is a text.
Please give me some advice
Thanks

MAT={'A','B','C','D','E','F'};
comb=nchoosek(MAT,3);
MAT='ABCDEF';
comb=nchoosek(MAT,3);
[m,n]=size(comb);
str='Det=[';
for i=1:m
   str=[str,'|',comb(i,1),'|*','|',comb(i,2),'|*','|',comb(i,3),'|,'];
end
str=[str(1:end-1),']'];
eval(str)
