The figures I'm interested in for this post are M <- matrix( c(20/33, -2/11, 8/33, 46/33) , ncol=2 ) A <- eigen (M)$vectors D <- diag(eigen(M)$values) N <- array( dim=c(11, 2) ) n0 <- matrix( c(2,1) ) N[1,] <- n0 for(i in 2:11){ N[i,] <- A %*% D^(i-1) %*% solve(A) %*% n0 } N <- In practice, this usually And in ecology, the world often is overdetermined, by which I mean simply that many different combinations of processes are sufficient to generate the observed data, with no one of them being necessary.
