چکیده
|
In this paper, a new and efficient approach is applied for numerical approximationof the linear differential equations with variable coefficients based on operational matriceswith respect to hermite polynomials. explicit formulae which express the hermite expansioncoefficients for the moments of derivatives of any differentiable function in terms of theoriginal expansion coefficients of the function itself are given in the matrix form. the mainimportance of this scheme is that using this approach reduces solving the linear differentialequations to solve a system of linear algebraic equations, thus greatly simplifying the problem.in addition, two experiments are given to demonstrate the validity and applicability of themethod.
