Some derivative-free solvers for numerical solution of SODEs
In this paper, some variants of stochastic solvers free from derivatives for Itˆo stochastic ordinary differential equations (SODEs) are given. The derived strong variants are convergent and explicit. Then, some implicit ...
A revisit of stochastic theta method with some improvements
Considering the stochastic theta method, in this work we discuss modified solvers for finding
the solution of It ˆo stochastic differential equations in the strong sense. It is observed that the proposed
variations ...
Iterative methods for nonlinear systems associated with finite difference approach in stochastic differential equations
We present some iterative methods of different convergence orders for solving systems of nonlinear equations. Their computational complexities are studies.Then, we introduce the method of finite difference for solving ...
Construction of some accelerated methods for solving scalar stochastic differential equations

A new solution method for stochastic differential equations via collocation approach
The objective of this paper is to propose a novel solution method for Itˆo stochastic differential
equations (SDEs). It is discussed that how the SDEs could numerically be solved as matrix problems.
To improve ...
A fast convergent numerical method for matrix sign function with application in SDEs
In this article, a new matrix iterative method for computing the sign of a matrix is offered.
Convergence along with asymptotical stability of the presented method is studied. An accelerated
form of the ...
On the computation of weighted Moore- Penrose inverse using a high-order matrix method
We propose a matrix method for calculating generalized weighted Moore-Penrose inverse numerically. It is proved that the scheme is convergent with high order via theoretical analysis. Some tests are also presented to show ...
An iterative method for computing the approximate inverse of a square matrix and the Moore–Penrose inverse of a non-square matrix
In this paper, an iterative scheme is proposed to find the roots of a nonlinear equation. It is
shown that this iterative method has fourth order convergence in the neighborhood of the
root. Based on this ...
