Is there any direct numerical code in Fortran77 to perform this task in complex variables algorithm without resorting to the splitting of variables and matrices into real and imaginary parts to form 2N real odes ? Many thanks. Regards, Sithi ------------------------------ From: Dirk Laurie Date: Fri, 2 May 1997 13:39:55 +0200 (SAT) Subject: Complex Analogues of Householder Reflections It is customary in numerical linear algebra texts to do things with real matrices until eigenvalues are reached, at which point it is reluctantly admitted that complex numbers are unavoidable. The Hermitian transpose is introduced, you tell the students that this is the true and correct definition of which the ordinary transpose is merely the real special case; a few theorems that really need unitary rather than orthogonal matrices (Schur's lemma, unitarily diagonalizable <==> normal) are proved; and the brief flirtation with complex matrices is over. Students are left with the impression that you can everywhere simply replace 'transpose' by 'Hermitian transpose' and all theorems will remain true --- an impression which is reinforced by having Matlab available, which works with complex matrices and Hermitian transposes as a natural way of life. This works well most of the time, but it does not work with Householder matrices the way they are usually introduced. All the books I have consulted use some inessential variation on the definition (1) H = I - 2*u*u' where norm(u)=1. (I'm using Matlab notation on purpose --- of course most of the books say u^T, not u^H, and work only with real u.) Some of the pleasant applications of Householder matrices are no longer true in the complex case, e.g. 1. For any two distinct vectors x and y of equal length, there exists a unique Householder matrix H such that H*x = y. 2. For any unit vector x except x=[1;0;0;...;0], there exists a unique Householder matrix with x as its first column. (1) is true only when x'*y is real, (2) only when x(1) is real. These facts are presumably well known to those who actually write codes for complex matrices (the computer is a much more unforgiving rejector of sloppy thinking than the typical undergraduate) but I found them out the hard way, having practically on the spur of the moment having written Hermitian transposes instead of ordinary ones, and discovering on my feet in front of a class that the old proofs no longer work, for the simple reason that the old theorems are no longer true. Perhaps the proper way to define elementary unitary matrices is: (2) H = (I-P) + w*P where P is a 1-dimensional orthogonal projector and abs(w)=1. Now in the real case H may equal I, which allows one to remove 'distinct' and 'except x=[1;0;0;...;0]' from the two lemmas above, and in the complex case the two lemmas are now true without further qualification. All that is lost is the term "Householder reflection": (2) is a reflection only when w=-1. If anyone knows a textbook that does treat elementary unitary matrices in this way, I would be delighted to hear of it -- I may consider switching texts!

We take into account that most of the research is now concentrated on finite elements for hard problems and on the fast solution of the resulting equations. Therefore the nonconforming elements and saddle point problems get as much space as the conforming elements. Moreover we treat the method of conjugate gradients and multigrid methods. Finally we present an introduction to the application of finite elements in solid mechanics which up to now does not exist in textbooks in a similar way. Many facts in finite element theory are counterintuitive for students who have studied ordinary differential equations before. We try to avoid that the reader overlooks the counterintuitive or unexpected arguments. People who have used the German edition for their lectures like especially an example with a tent in connection with the trace theorem for Sobolev spaces. But we find counterintuitive things at all levels. Just recently it has turned out that saddle point problems with penalty terms have a different behavior than one from folklore. The book has 6 chapters: I. Introduction II. Conforming Finite Elements III. Nonconforming and Other Methods IV. The Conjugate Gradient Method V. Multigrid Methods VI. Finite Elements in Solid Mechanics We intend to establish later a www page with additional remarks and a list of misprints. ------------------------------ From: Michael Guenther Date: Mon, 28 Apr 1997 16:34:27 MESZ Subject: Workshop on Scientific Computing in Electrical Engineering Workshop "Scientific Computing in Electrical Engineering: electrical circuits --- electromagnetic fields" Technische Hochschule Darmstadt, June 18-20, 1997 Organisation: Fachgruppe "Scientific Computing" of the "Deutschen Mathematiker Vereinigung" (DMV) Dr. M.
