**Subject: Re: Query About Rounding Error**

I'll take the opportunity of Pete Stewart's query concerning real-life

embarrassments due to rounding error to mention that I have a web page,

http://www.math.psu.edu/dna/disasters/, on real-life disasters

attributable to bad numerics, It reports on the failure of the Patriot

Missile battery at Dharan, which is directly attributable to

accumulation of round-off errors, and also on the explosion of the

Ariane 5, which was caused by an overflow, and the loss of the Sleipner

offshore platform, which was due to bad finite element technology. In

each case I studied the investigative reports, but just posted a small

summary to whet the appetites of my students.

I would be interesting to hear of other events that fit this

description. I find that these can be great student motivators.

David Stewart replies:

I don't think it is anything to worry about... in any case

MATLAB can't tell the difference between a scalar and a 1 x 1

matrix because there is no scalar "type" in MATLAB.

The question remains: Is this potentially dangerous?

Should there be a scalar type in MATLAB, and should we be

required to write something like

scalar(A*B)*C

for the product to work?

Here's why I don't think we need it:

A re-associated product (what we get by re-arranging the

parentheses) will only be defined if the 1 x 1 matrix

and scalar interpretations are both correct.

If we have a product A_1*A_2*...*A_p, if some sub-expression is

a scalar (say A_i*...*A_j), then A_i is 1 x n_i and A_j is m_j x 1.

If we try to re-associate this product from

A_1*...*A_{i-1}*(A_i*...*A_j)*A_{j+1}*...*A_p,

to

A_1*...*A_r*(A_{r+1}*...*A_{i-1}*A_i*...*A_s)*...*A_p,

it will only work if A_{i-1} is m_{i-1} x 1. If s > j then we would

also need A_{j+1} to be 1 x n_{j+1}. Then the 1 x 1 matrix and

scalar interpretations are equivalent. If s = j, then

A_{r+1}*...*A_{i-1}*A_i*...*A_s is an m_{r+1} x 1 matrix.

Then we can only multiply by (A_{s+1}*...) if A_{s+1} = A_{j+1} is

a 1 x n_{j+1} matrix. Thus the 1 x 1 matrix and scalar interpretations

are equivalent in this case as well. If we choose A_i*...*A_j

to be a minimal product where m_i = 1 and n_j = 1, then if s < j,

n_s is not equal to one, and A_{s+1} has m_{s+1} not equal to one

either. Then following through with the matrix rules, we see that

the product that follows A_s up to A_j is associative, and this

reduces the question to the previous case (s = j).

So if MATLAB can do the product, the result is independent of whether

1 x 1 matrices are treated as matrices or scalars.

If you had some software that didn't check the matrix compatibility

condition (n_i = m_{i+1} for all i) then you would have reason

to worry.

Austin Dubrulle replies:

1. Ilse's question is pertinent, but there should be "something to worry

about" only when teaching a freshman class in linear algebra with MATLAB

(see item 2 below). For that purpose, MATLAB is no substitute for a brain,

a no. 2 pencil, a writing tablet, and MacLane/Birkhoff or Bourbaki.

Otherwise, for anyone who has background in mathematics and who uses MATLAB

as a programming language, there is little to worry about.

2. The MATLAB guide annonces up front that the only data type for

computational linear algebra is "matrix," i.e., a column vector is an mx1

matrix, a row vector, a 1xn matrix, and a scalar, a 1x1 matrix. This, of

course, defines an algebra that is a bit different from matrix algebra.

Under these conditions, multiplication of a column vector by a MATLAB

scalar should be written as

(1) 'vector*scalar' and not 'scalar*vector.'

The opposite is true for the scalar multiplication of a row vector. The

multiplication of a matrix by a scalar should not exist, only the

multiplication by the proper diagonal matrix. There are more such quirks.

Yet, at the cost of a violation of matrix algebra---the conflation of the

1x1 matrix and the scalar definitions---things become simpler, so that both

expressions (1) are acceptable, and so is the multiplication of a matrix by

a 1x1 matrix. Since the field of 1x1 matrices is isomorphic to the field of

complex numbers, the violation is mild in its practical consequences.

Yet, the 1x1 matrix ends up having two personalities, each of which being

determined by expression context. Perhaps the MATLAB manual should

emphasize this peculiarity instead of bluntly asserting that "a scalar is a

1x1 matrix."

3. Given MATLAB's matrix definition, someone concerned about algebra should

not write

(2) A*B*C

with A=[1 1], B=[1 1]', and C=[1 2 3]', but

(3) C*A*B

which, of course, formally gives the same result, and respects

associativity. In fact, I suspect that most of us mean (3) when writing

(2). It turns out that MATLAB has an order of operation that makes (2)

acceptable. But why not write the expression as (3) in the first place, in

the form C*(A*B) as a concession to efficiency of operation? Or (A*B)*C?

I think that MATLAB should not be considered as the strict embodiment of an

algebra, but as a convenient computational engine that gets useful things

done without too much pain and suffering, and delivers decent performance.

It can do that because of pragmatic design choices, not unlike FORTRAN in

that respect. Other languages that enforce rigid, saintly syntaxes

(algebras) along with attendant limitations---e.g., PASCAL---have not been

too useful outside CS departments.

Can be ordered now through amazon.com or bn.com.

Go to URL www.ece.nwu.edu/~nocedal/num-opt.html for further

information on contents and ordering.

NUMERICAL OPTIMIZATION presents a comprehensive and up-to-date

description of the most effective methods in continuous

optimization. It responds to the growing interest in optimization in

engineering, science, and business by focusing on the methods that are

best suited to practical problems.

Drawing on their experiences in teaching, research, and consulting,

the authors have produced a textbook that will be of interest to

students and practioners alike. Each chapter begins with the basic

concepts and builds up gradually to the best techniques currently

available.

Because of the emphasis on practical methods, as well as the extensive

illustrations and exercises, the book is accessible to a wide

audience. It can be used as a graduate text in engineering, operations

research, mathematics, computer science, and business. It also serves

as a handbook for researchers and practitioners in the area.

Above all, the authors have strived to produce a text that is pleasant

to read, informative, and rigorous---one that reveals both the

beautiful nature of the discipline and its practical side.

Modelling the Response of Materials in Manufacturing Processes

Chris Bailey C.Bailey@greenwich.ac.uk

Stanly Steinberg stanly@math.munm.edu

A wide range of industrial processes are governed by complex sets of physics

such as fluid flow, heat transfer with solidification, electromagnetics, solid

deformation, etc. Materials used within the process may also be inhomogeneous.

Predicting such phenomena provides a number of challenges for the modelling

community.This mini-workshop will focus on the modeling techniques used to

simulate manufacturing processes that may involve distinct or interacting

physics. Appropriate discretization methods for such modelling will also be

discussed.

The organizers will organize a special issue of Journal of Applied

Mathematical Modelling based on the papers presented in this mini-workshop.
