A quadratic spline difference scheme for a self-adjoint boundary value problem


Katarina Surla




The exponentially fitted quadratic spline difference scheme for the problem: $\varepsilon y''+q(x)y=f(x)$, $0<x<1$, $y(0)=\alpha_0$, $y(1)=\alpha_1$ is derived. The scheme has a second order accuracy, under some conditions, on the functions $q$ and $f$. The numerical results are also given.
