A matrix is a rectangular array of numbers, symbols, or expressions arranged in rows and columns. They are a crucial part of linear algebra and have various applications in fields like engineering, ...

This Mathematica script offers tools for solving linear systems and analyzing matrix properties. It includes various solving methods, matrix operations, and visualizations. Solvers: Inverse, LU, QR, ...

This Rust program shows how to solve a system of linear equations using matrix inversion using the nalgebra library. It takes a $2\times2$ coefficient matrix and a 2-dimensional result vector, then ...

A new method for solving the 1D Poisson equation is presented using the finite difference method. This method is based on the exact formulation of the inverse of the tridiagonal matrix associated with ...

Abstract: In this paper, five iterative methods for solving two coupled fuzzy Sylvester matrix equations are considered. The two coupled fuzzy Sylvester matrix equations are expressed by using the ...

The aim of this study is to give a Legendre polynomial approximation for the solution of the second order linear hyper-bolic partial differential equations (HPDEs) with two variables and constant ...

Abstract: Many problems in systems and control theory are related to solvability of Sylvester matrix equations. In many applications, at least some of the parameters of the system should be ...

Solve the equation \(\frac{3s + 9}{4} = 7\). This means \(3s + 9\) has all been divided by 4. To solve the equation, inverse the operations. The opposite of dividing by 4 is multiplying by 4. Any ...
