I have a matrix:

R=[1 2 1 3 2 3 1;1 1 2 1 2 2 3];

that i want to convert to:

Q=["A11","A21","A12","A31","A22","A32","A13"];

How can I do that?

Appreciated!

R=[1 2 1 3 2 3 1;1 1 2 1 2 2 3]
R = 2×7
     1     2     1     3     2     3     1
     1     1     2     1     2     2     3
compose("A%d%d", R(1,:).', R(2,:).').'
ans = 1×7 string array
    "A11"    "A21"    "A12"    "A31"    "A22"    "A32"    "A13"
