Hi Dear All,
I have an array of 1*4, in which each array can be of two strings 'H' or 'C'. to elaborate on it more this can be like below:
[H H H H] or [H H H C] or [H C C C] or ..........[C C C C}
in total there would be 2*2*2*2=16 case for that.
I would like to generate all the 16 cases and following that I want to proceed the calculations. I dont know how to form these 16 cases and cover all the possible cases for that.
I would appreciate your support in advance.

If you mean actual strings instead of chars, then:
A = dec2bin(0:15);
A(A=='1') = 'H';
A(A=='0') = 'C';
A = string(num2cell(A))
A = 16×4 string array
"C" "C" "C" "C" "C" "C" "C" "H" "C" "C" "H" "C" "C" "C" "H" "H" "C" "H" "C" "C" "C" "H" "C" "H" "C" "H" "H" "C" "C" "H" "H" "H" "H" "C" "C" "C" "H" "C" "C" "H" "H" "C" "H" "C" "H" "C" "H" "H" "H" "H" "C" "C" "H" "H" "C" "H" "H" "H" "H" "C" "H" "H" "H" "H"

Another possible solution:
[p,q,w,s] = ndgrid({'H','C'});
A = [p(:),q(:),w(:),s(:)];
{'H'} {'H'} {'H'} {'H'} {'C'} {'H'} {'H'} {'H'} {'H'} {'C'} {'H'} {'H'} {'C'} {'C'} {'H'} {'H'} {'H'} {'H'} {'C'} {'H'} {'C'} {'H'} {'C'} {'H'} {'H'} {'C'} {'C'} {'H'} {'C'} {'C'} {'C'} {'H'} {'H'} {'H'} {'H'} {'C'} {'C'} {'H'} {'H'} {'C'} {'H'} {'C'} {'H'} {'C'} {'C'} {'C'} {'H'} {'C'} {'H'} {'H'} {'C'} {'C'} {'C'} {'H'} {'C'} {'C'} {'H'} {'C'} {'C'} {'C'} {'C'} {'C'} {'C'} {'C'}
