Time and space efficient generators for quasiseparable matrices

Abstract

The class of quasiseparable matrices is defined by the property that any submatrix entirely below or above the main diagonal has small rank, namely below a bound called the order of quasiseparability. These matrices arise naturally in solving PDE’s for particle interaction with the Fast Multi-pole Method (FMM), or computing generalized eigenvalues. From… (More)
