Abstract: On the basis of the differential equations of stellar structure and its boundary conditions,the difference equations are obtained in the form of vector functions.The New ton-Raphson method allows transfering the difference equations in to a matrix equation in vector algorithm which is solvable.

Key words: astrophysics, stellar structure, non-linear differential equations
