Reliable numerical methods for polynomial matrix triangularization

Numerical procedures are proposed for triangularizing polynomial matrices over the eld of polynomial fractions and over the ring of polynomials. They are based on two standard polynomial techniques: Sylvester matrices and interpolation. In contrast to other triangularization methods, the algorithms described in this paper only rely on well-worked numerically reliable tools. They can also be use...

Numerical Experiments with Toeplitz Matrix Approximation Methods

Positive semidefinite Toeplitz matrix constraints arise naturally in a variety of problems in engineering. This paper deals with the numerical of this problem. Our approach is based on (i) interior point primal-dual path-following method; (ii) a projection algorithm which converges globally but slowly; (iii) the filterSQP method which is faster. Hybrid methods that attempt to combine the best f...
