Pre-service mathematics teachers’ mental constructions when using Cramer’s rule

South African Journal of Education, 2019
This study explored the mental constructions displayed by pre-service mathematics teachers (PMTs) when applying Cramer’s rule. The aim was to reveal the character of mental constructions made around the nature of the solution set of equations and the ...

The core inverse and constrained matrix approximation problem

Open Mathematics, 2020
In this article, we study the constrained matrix approximation problem in the Frobenius norm by using the core inverse:||Mx−b||F=minsubjecttox∈ℛ(M),||Mx-b|{|}_{F}=\hspace{.25em}\min \hspace{1em}\text{subject}\hspace{.25em}\text{to}\hspace{1em}x\in ...

The explicit formula for Gauss-Jordan elimination applied to flexible systems

Special Matrices, 2022
Flexible systems are obtained from systems of linear equations by adding to the elements of the coefficient matrix and the right-hand side scalar neutrices, which are convex groups of (non-standard) real numbers.

Multiparameter Inversion: Cramer's Rule for Pseudodifferential Operators

International Journal of Geophysics, 2011
Linearized multiparameter inversion is a model-driven variant of amplitude-versus-offset analysis, which seeks to separately account for the influences of several model parameters on the seismic response.

Future orientation and planning in forestry: a comparison of forest managers' planning horizons in Germany and the Netherlands [PDF]

, 2009
Long range (or strategic) planning is an important tool for forest management to deal with the complex and unpredictable future. However, it is the ability to make meaningful predictions about the rapidly changing future that is questioned.

Solution of the system of the 2-refined neutrosophic linear equations by using Cramer’s rule [PDF]

Neutrosophic Sets and Systems
In this paper, we introduced Cramer's rule for solving a system of the 2-refined neutrosophic linear equations. We defined the general form of the 2-refined neutrosophic linear equations and generalized this to system of the 2-refined neutrosophic linear

Membangkitkan Suatu Matriks Unimodular Dengan Python

Jurnal Derivat, 2018
An SPL can be represented as a multiplication of the coefficient matrix and solution vector of the SPL. Determining the solution of an SPL can use the inverse matrix method and Cramer's rule, where both can use the concept of the determinant of a matrix.
