Subject: paper wanted
I am looking for some typed notes written by J.L Howland of
the University of Ottawa entitled
"On the construction of gaussian quadrature formulae"
from around 1975.
I earlier sent this request to a group of quadrature people
but the notes didn't turn up. Howland is away from UofO
and they won't tell me where he is.
If anyone has these notes please mail to me before sending them
so that I can ensure that multiple copies don't swamp the
US mail system.
Thanks,

Subject: Eigenvector Eigenvalue Test Suite

I'm not usually involved with this type of thing, but I've just found
myself in need of an Eigenvector/value routine. Since I haven't
worked in FORTRAN in a *very* long time, I decided to copy the
Jacobi transformation routine from "Numerical Recipes" into Lisp.
My problem: I think I have it working, but I don't have enough
known solutions to test it with. Does anyone have a set of symmetric
matrices and their eigenvectors and normalized eigenvalues that I
can use as a test suite? The routine that I coded is, I believe,
JACOBI out of EISPACK, so if anyone has run a set of matrices through
JACOBI recently, I'd love to see the results.
Thanks,
