[Lapackpp-devel] Pseudoinverse, Eigenvalues and Eigenvectors

[Jacob \(Jack\) G. <jg...@cs...>]

Just wondering if there's a fast way to do the following with lapack++ (if
not, then in LAPACK) to do the following functions:

a) Pseudoinverse (maybe I should do inv(A'A)A', but inv() needs to be done
via solving the linear equation AA'=I (is there a faster way to do this?)

b) Get eigenvectors and eigenvalues of a general matrix?  (or even of a
symmetric matrix)?

Let me know

Thanks

Jack
