Convergence of the 2-Point Diagonally Implicit Super Class of BBDF with Off�?¢�?�?��?Step Points for Solving Stiff IVPs

[摘要] The 2-point Diagonally Implicit Superclass of BBDF with off-step point’s method proposed by Babangida had been studied and further established the necessary conditions for its convergence. Consistency, zero stability and order of the method are discussed.
