In this chapter we present algorithms and error analysis of numerical methods for solving linear systems \\(Ax=b\\) with nonsingular square matrices. Here we present only direct methods. They are called direct because in the absence of rounding errors they would give the exact solution of \\...
The purpose of the study was to explore the role of prerequisite concepts of determinant and matrix inverse in solving systems of equations using the inverse matrix method. The Action-Process-Object-Schema (APOS) theoretical framework was used to analyse the 116 participants' written responses to ...
Solving high-order nonlinear differential equations using operational matrix based on exponential collocation method In this paper, the exponential approximation is applied to solve high-order nonlinear differential equations. The main idea of this method is based on the ... M Aslefallah,S Abbasbandy...
Specifically, a theoretical analysis is presented of the numerical errors arising from the use of the ensemble mean (to approximate the mean) in the drift term in the Langevin equations. Previously [12], this approximation has been shown empirically to lead to significant bias. The following ...

In this paper, we present an analytical solution for different systems of differential equations by using the differential transformation method. The conve... AH Hassan - 《Applied Mathematical Modelling》 被引量: 122发表: 2008年 Application of the homotopy analysis method to solving nonlinear evoluti...
The numerical solutions to the singular integral equations obtained by the fracture mechanical analyses of a cracked wedge under three different conditions are considered. The three considered conditions are: (i) a radial crack on a wedge with a nonfinite radius under the traction-traction boundary ...

The students do not possess, even at grade 8, the algebraic tools for solving systems of linear equations. Therefore, in order to solve these problems, we expect them to engage in trial and error, and to take into account the result of one or more trials in order to propose another one...
Convenience of using large data. 3. Consistent solutions over the full space of parameters. As for (1), it can be said that highly complicated PDEs systems with a very large number of parameters and high dimensionality, can be implemented in Python Language using TensorFlow, and PyTorch in hu...
