SVD update methods for large matrices and applications
Juan Manuel Peña, Tomas Sauer
We consider the problem of updating the SVD when augmenting a "tall thin" matrix, i.e., a rectangular matrix $A \in \RR^{m \times n}$ with . Supposing that an SVD of i…
Hankel and Toeplitz operators of finite rank and Prony's problem in several variables
Tomas Sauer
Prony's problem in several variables has attracted some attention recently and provides an interesting combination of polynomial ideal theory with analytic and numeric computations…
Filters for anisotropic wavelet decompositions
Mariantonia Cotronei, Milvia Rossini, Tomas Sauer +1
Like the continous shearlet transform and their relatives, discrete transformations based on the interplay between several filterbanks with anisotropic dilations provide a high pot…
Numerical computation of H-bases
Masoumeh Javanbakht, Tomas Sauer
This paper gives a numerically stable method to compute H-basis which is based on the computing a minimal basis for the module of syzygies using singular value decomposition. We il…
Generalized Taylor operators and Hermite subdivision schemes
Jean-Louis Merrien, Tomas Sauer
Hermite subdivision schemes act on vector valued data that is not only considered as functions values in , but as consecutive derivatives, which leads to a mild form…
Level-dependent interpolatory Hermite subdivision schemes and wavelets
Mariantonia Cotronei, Caroline Moosmüller, Tomas Sauer +1
We study many properties of level-dependent Hermite subdivision, focusing on schemes preserving polynomial and exponential data. We specifically consider interpolatory schemes, whi…
