Abstract
This chapter considers the product A=A1A2 of block matrices \(A_{1}=\{A^{(1)}_{ij}\}^{N}_{i,j}=1\) and \(A_{1}=\{A^{(2)}_{ij}\}^{N}_{i,j}=1\) with block entries of compatible sizes m i× v j and v i× n j.One assumes that quasiseparable generators of the factors are given and one derives formulas and algorithms to compute quasiseparable generators of the product.
