The method is formulated from continuous schemes obtained via. collocation and interpolation techniques and applied in a block-by-block manner as numerical integrator for first, second and third order ODEs. The convergence properties of the method are discussed via. zero-stability and consistency. Numerical examples are included and comparisons are made with existing methods in the literature. ER -
