left eigenvector
What about the following:
> A <- array(1:4, dim=c(2,2))
> leftA <- eigen(t(A))
> t(leftA$vectors)
[,1] [,2]
[1,] -0.4159736 -0.9093767
[2,] -0.8245648 0.5657675
hope this helps. spencer graves

Federico - If a matrix is symmetric, its left and right eigenvectors are identical. If a matrix is not symmetric, its left eigenvector is the right eigenvector of its transpose. However, without checking, I don't recall which R functions will return the correct right eigenvectors for a non-symmetric matrix. - best - tom blackwell - u michigan medical school - ann arbor - On Thu, 12 Feb 2004, Federico Calboli wrote:
Dear All, how do I compute the left eigenvector of a matrix? I gather that "eigen" computes the right eigenvectors... Regards, Federico Calboli -- ================================= Federico C. F.
