Numerical Solution of Nonlinear Stochastic Differential Equations by Block Pulse Functions with Improved Operator Matrix
摘要
Abstract
This paper introduces an effective numerical method based on the block pulse functions with improved operator matrix to solve the nonlinear stochastic differential equations.The nonlinear stochastic differential equation is transformed into a set of algebraic equations by the improved operator matrix of block pulse function.Furthermore,we perform an error analysis and demonstrate that the method converges faster.Finally,numerical examples are used to support the method.关键词
