Second derivative Hybrid Block Backward Differentiation Formulae for Numerical Solution of Stiff Systems

Y. Skwame, G. M. Kumleng & I. A. Bakari · Journal of Advances in Mathematics and Computer Science · 2017

In this research work, two and three step second derivative hybrid block backward differentiation formulae (SDHBBDF) method of order 6 and 7 are presented for the numerical solution of stiff initial value problems. The block scheme was obtained through increasing the number k in...
