The Kronecker ProductMatrices arising from 2D and 3D problems sometimes have a Kronecker product structure. Identifying a Kronecker structure can be very rewarding since it simplifies the derivation of properties of such matrices.

The Singular Value Decompositionpplications include solving over-determined equations, principal component analysis in statistics, numerical determination of the rank of a matrix, algorithms used in search engines, and the theory of matrices.

Orthonormal and Unitary Transformationsngular form and more generally a rectangular matrix to upper triangular (also called upper trapezoidal) form. This lead to a decomposition of a rectangular matrix known as a . and a reduced form which we refer to as a .. The QR decomposition and factorization will be used in later chapters to solve least squares- and eigenvalue problems.

Least Squaresay a .-norm, and look for . which minimizes .. The use of the one and . norm can be formulated as linear programming problems, while the Euclidian norm leads to a linear system and has applications in statistics. Only this norm is considered here.

The Conjugate Gradient Methodo not have to estimate any such parameter. However the conjugate gradient method is restricted to positive definite systems. We also consider a mathematical formulation of the .. It is used to speed up convergence of the conjugate gradient method. We only give one example of a possible preconditioner.
