Abstract :Abstract. In this paper a model has been solved using Laguerre spectral method with two different basis functions. Unlike classical method, all the boundary conditions will be satisfied using linear combination of Laguerre functions as basis functions. Numerical results show that using a new basis has less error and also leads to three diagonal matrix that has a conditions number which is smaller than that of the classical method.Keywords : Linear differential equations, Basis functions, Combination of Laguerre functions, Laguerre spectral method
