Square Matrices,it is useful to consider matrices with entries in a ring. This allows us to consider matrices with entries in ℤ (rational integers) as well as in .[.] (polynomials with coefficients in .). We shall assume that the ring . of scalars is a commutative (meaning that the multiplication is commutative) in

Norms, the eigenvalues of .: .When . =ℝ, one takes into account the complex eigenvalues when computing .(.)..The scalar (if . =ℝ) or Hermitian (if . =ℂ) product on . is denoted by .. The vector space . is endowed with various norms, pairwise equivalent since . has finite dimension (Proposition 4.1.3 below

Matrix Factorizations,many times with various values of b. In the next chapter we shall study iterative methods for the case .=ℝ or ℂ. Here we concentrate on a simple idea: To decompose . as a product . in such a way that the resolution of the intermediate systems . = . and . = . is “cheap”. In general, at least one of t

Iterative Methods for Linear Problems,. is invertible. For example, if . admits an . factorization, the successive resolution of . = ., . = . is called the .. When a leading principal minor of . vanishes, a permutation of the columns allows us to return to the generic case. More generally, the Gauss method with pivoting consists in perm

Approximation of Eigenvalues,ute the characteristic polynomial and then find its roots, turns out to be hopeless because of Abel’s theorem, which states that the general equation . = 0, where . is a polynomial of degree . ≥ 5, is not solvable using algebraic operations and roots of any order. For this reason, there e xists no d
