Abstract. Higher order boundary value problems (BVPs) play an important role modeling various scientific and engineering problems. A general recipe for a order BVPs is sparse (for any natural number ).
In this article we develop an efficient numerical scheme for linear order BVPs. First we convert the higher order BVP to a system of first order BVPs. Then we use Tchebychev polynomials to approximate the solution of the BVP as a weighted sum of polynomials. We collocate at Tchebychev clustered grids to generate a system of equations to approximate the weights for the polynomials. The excellency of the numerical scheme is illustrated through some examples.
