Subject: First Courses in Numerical Analysis

Dear colleagues,

I would like to know who gave, in each country, the first "real" course in
numerical analysis. If you have any information, could you please write me,
giving as much details as possible: name of the teacher, name of the course,
university where it was given, dates, contents of the course, etc.
I thank everyone in advance.

Subject: Looking for Large Generalized Eigenvalue Problems

We have developed a parallel program that computes the small extreme
eigenvalues of A x = lambda B x, where A is symmetric (possibly indefinite)
and B is SPD. It uses the CG iteration to minimize the Rayleigh quotient.
Since the Rayleigh quotient for the generalized eigenvalue problem
is not a quadratic function of x, so far there is no known mathematical
proof, but it is working. Recently, we have developed a new parallel
preconditioner and it seems to work better than the classical Incomplete
Chelesky factorization. We have tested our program on 5-point Laplacian and
some ill-conditioned problems from Harwell-Boeing on the CRAY-T3E with B=I.
We are looking for some real applications for which our method will be useful.
Also, we will make available our program on the internet, which is written
in Fortran-77 with MPI library.

Subject: Seeking Code for QD Algorithm

Dear Colleagues,

I would greatly appreciate it if you could let me know whether
there is a Code for the quotient-difference algorithm, Rutishauser's
rule; (i.e computing poles of meromorphic functions/poles
with equal moduli of meromorphic functions).

Thank you in advance.

Help with discretization

Dear members of this list:

I am working on the first order linear partial differential equations of
MacKendrick VonFoerster type and wish to discretize the time variable
only, so as to obtain a difference-differential equation. Please kindly
help. Also, how can obtain the dicrete version of the following interation
function F(u(t,a); v(t,a)), ,where u(t,a), is the population density of
males and v(t,a) for females.

Subject: Question on Kronecker Products


I have a question related to finding charecterization of a matrix
involving the kronecker product and I can't seem to be able to crack it.
Please let me know if anyone had seen similar problem I will pose


uppercase letters --------matrices
.kron symbol for kronecker product of two matrices

'P' ---- 2*m x m matrix
'I' ---- 2*m x 2*m identity matrix
'B' ---- 2*m x 2*m matrix with all elements zero except lower
super diagonal elements, some of these also can be zero

|0 0 0 0 0|
|1 0 0 0 0|
B=|0 0 0 0 0|
|0 0 1 0 0|
|0 0 0 1 0|

then C=[I B] is a matrix formed by augmenting B to I
clearly C is full rank then
for the matrix
D= C.kron P =[P B*P] is a (2*m x 2*m) matrix
for D to be full rank
what is the condition on P ?
how to characterize P ?

Yours sincerely

Subject: A Mathematics Metasearch Facility

A preliminary version of a Mathematics Metasearch Machine
is available at

The site is suitable for cross disciplinary search and
in addition to being a list of links it allows for simple
one-step search of several sites.

To paraphrase a famous quote "If we see far it is because
we are perched on the shoulder of giants." In other words
this site does not offer an independent database. However,
plans are underway to remedy that shortcoming in about 18
months. Meanwhile please forward suggestions, corrections and
additions to me.

For now our goal is to list sites that
a) Have an English version
b) Contain substantial, reusable, focused, categorized
mathematics covering a subspecialty (as in a chapter
of an encyclopedia or a category in MR)
Once our database comes on line we will use a finer mesh
to collect information.

2 postdoctoral positions of one year are opened in the CHPV team (Calcul Haute
Performance et Validation) of the LIP6 Laboratory (Laboratoire d'Informatique
de Paris 6). A tool for numerical validation, the CADNA library, has been
developed to control the round-off error propagation in scientific codes
using the floating-point arithmetic. This library is available for the C,
Fortran and ADA language. The use of CADNA requires modifications for its
implementation on classical codes.

The aim is to develop pre-compilers for an automatic implementation of CADNA
for the three language. An interface for informations on accuracy of results
provided by CADNA is also part of the work.

Motivated candidates must have experience in any or all of the following
syntaxic analysis,
C, Fortran or ADA languages,
General Unix systems and Linux in particular,
General knowledge in scientific computing.
