Diagonally Implicit 2-Point Block Backward Differentiation Formula With Two Off-Step Points For Solving Stiff Initial Value Problems
A diagonally implicit form of the 2-point block backward differentiation formula (BDF) with two off-step points is developed for solving stiff initial value problems. The method is derived by introducing a lower triangular matrix in the coefficient matrix of the existing 2-point block BDF method with off-step points for solving stiff ordinary diffe...
