NON-INTERIOR CONTINUATION METHOD FOR COMPLEMENTARITY PROBLEMS IN ABSENCE OF STRICT COMPLEMENTARITY
SUN, MIN; SHI, ZHEN-JUN - In: Asia-Pacific Journal of Operational Research (APJOR) 23 (2006) 01, pp. 107-122
In this paper, by using a modified smoothing function, we propose a new continuation method for complementarity problems with R0-function and P0-function in the absence of strict complementarity. At each iteration, the continuation method solves one linear system of equations and performs one...

A note on computation of pseudospectra
Janovská, Drahoslava; Janovský, Vladimír; Tanabe, Kunio - In: Mathematics and Computers in Simulation (MATCOM) 82 (2012) 10, pp. 1732-1743
The aim is to contribute to pseudospectra computation via a path following technique. Given a matrix A∈ℂn×n, we compute the branch consisting of a fixed singular value ϵ and corresponding left and right singular vectors of the parameter dependent matrix (x+iy)I−A. The fact that the...
