Two low accuracy methods for stiff systems. (English) Zbl 1024.65053
Summary: Two low accuracy explicit one-step methods for stiff ordinary differential equations are extended directly to solve systems of equations. Some defects of the component form of these methods are avoided. To perform these, a new set of vector computations are introduced. Some numerical experiments are presented to show the superiority of the new methods.
