n = 872

4   Pass
m=1; n=1024 Ack = n+2; assert(isequal(ackermann(m,n),Ack))

n = 1024

5   Pass

n = 1

9   Fail
m=4; n=0; Ack = 13; assert(isequal(ackermann(m,n),Ack))

Index in position 2 exceeds array bounds (must not exceed 1). Error in ackermann (line 7) if tAck(m+1,n+1) > 0 Error in ackermann (line 12) [vAck, tAck] = ackermann(m - 1, 1, tAck); Error in Test9 (line 4) assert(isequal(ackermann(m,n),Ack))

10   Pass
