EXAMPLE
We have A[2](1,1)=1, A[1](1,2)=1, A[0](1,3)=1 and so A[3] = A[3-1] + A[3-1] + A[3-1] = 3A[2], a matrix with entries (3,3,6,3,3,6,12,18,33), yielding the 28th, 29th, ..., 36th terms of the sequence.
MAPLE
with(linalg): A[0]:=matrix(3, 3, [0, 1, 1, 1, 1, 2, 1, 2, 4]): A[1]:=matrix(3, 3, [1, 1, 2, 1, 1, 2, 2, 4, 7]): for n from 2 to 10 do A[n]:=evalm(A[n-A[n-1][1, 1]]+A[n-A[n-2][1, 2]]) od: seq(seq(seq(A[k][i, j], j=1..3), i=1..3), k=0..10);
