  Fraction-free row reduction of matrices of skew polynomials
Beckermann B., Cheng H., Labahn G.  Symbolic and algebraic computation (Proceedings of the 2002 international symposium, Lille, France, Jul 7-10, 2002) 8-15, 2002.  Type: Proceedings

Skew polynomials are very useful in symbolic computation and algebra to uniformly model problems involving differential or difference operators. This paper is devoted to introducing a new algorithm, computing the row reduction of a mat...

  When are two numerical polynomials relatively prime?
Beckermann B., Labahn G. Journal of Symbolic Computation 26(6): 677-689, 1998.  Type: Article

The authors discuss testing the relative primality of twopolynomials that are given with inexact coefficients or, in other words,testing whether two polynomials will always remain relatively prime (orcoprime) even if their coefficients...

  Algorithm 766: experiments with a weakly stable algorithm for computing Padé-Hermite and simultaneous Padé approximants
Cabay S., Jones A., Labahn G. ACM Transactions on Mathematical Software 23(1): 91-110, 1997.  Type: Article

The Fortran implementation of an iterative lookahead algorithm for the computation of a diagonal of the Padé tables of Padé-Hermite and simultaneous Padé systems is described. The results of the computation i...

  Algorithms for computer algebra
Geddes K., Czapor S., Labahn G., Kluwer Academic Publishers, Norwell, MA, 1992.  Type: Book (9780792392590)

The subject of computer algebra deals with the use of computers in manipulating (processing) symbolic mathematical objects in addition to numerical objects. Nonnumeric processing like compilation or word processing is not part of compu...

  The inverses of block Hankel and block Toeplitz matrices
Labahn G., Chio D., Cabay S. SIAM Journal on Computing 19(1): 98-123, 1990.  Type: Article

The primary contribution of this paper is a set of closed formulas for inverses of block Hankel matrices H. These formulas have the advantage of requiring only that H itself be nonsingular. Many fast algorithms for comput...
