Abstract: Interpolating matrix method is a numerical method for solving multi-point boundary value problems. This paper provides the error analysis of the method, proving the same precision for the solutions y(x), y'(x), ..., y(m)(x)obtained by the method. Author gives the convergence order estimate and proves good stability property of the method the second order scalar equations.
