Matrix Structures and Matrix Functions

Proceedings of the 2023 International Symposium on Symbolic and Algebraic Computation, 2023
Structured matrices play a relevant role in symbolic and numerical computations. In the literature and in applications we encounter several types of structure, which are typically related to the properties of the problems they stem from: banded structure is often associated with locality of functions or operators, Toeplitz structure arises from shift ...

Matrix Functions and Matrix Equations

2015
Matrix functions and matrix equations are widely used in science, engineering and social sciences due to the succinct and insightful way in which they allow problems to be formulated and solutions to be expressed.

The matrix sign function [PDF]

IEEE Transactions on Automatic Control, 1995
A survey of the matrix sign function is presented including some historical background, definitions and properties, approximation theory and computational methods, and condition theory and estimation procedures, Applications to areas such as control theory, eigendecompositions, and roots of matrices are outlined, and some new theoretical results are ...

Matrix Metalloproteinases and Platelet Function

2017
Platelets contain and release several matrix metalloproteinases (MMPs) and their tissue inhibitors of matrix metalloproteinases (TIMPs), including MMP-1, -2, -3, -9, and -14 and TIMP-1, -2, and -4. Although devoid of a nucleus, platelets also synthesize TIMP-2 upon activation.

Matrix functions and applications: Part II — Functions of a matrix

IEEE Spectrum, 1964
In Part II of this series, differential equations with constant matrix coefficients are introduced. These equations may be solved explicitly by finding the eigenvalues and by expressing the functions of a diagonal matrix in terms of its constituent ...

A Simplex Method for Function Minimization

Computer/law journal, 1965
A method is described for the minimization of a function of n variables, which depends on the comparison of function values at the (n 41) vertices of a general simplex, followed by the replacement of the vertex with the highest value by another point ...

What mouse mutants teach us about extracellular matrix function.

Annual Review of Cell and Developmental Biology, 2006
For many years the extracellular matrix was viewed as a benign scaffold for arranging cells within connective tissues, but it is now being redefined as a dynamic, mobile, and flexible key player in defining cellular behavior.

Transfer matrix function (TMF) for wave propagation in dielectric waveguides with arbitrary transverse profiles

, 1998
A transfer matrix function (TMF) is derived for the analysis of electromagnetic (EM) wave propagation in dielectric waveguides with arbitrary profiles, situated inside rectangular metal tubes.

R-matrix and S-matrix strength functions

Nuclear Physics A, 1968
Abstract Strength functions are defined for both R - and S -matrices as the energy average of the ratio of pole residues to pole spacings. The R -matrix strength functions exhibit no threshold effects, while the S -matrix strength function for channel c considered as a function of the energy has a branch point at that channel threshold ...
