Exponential integrators represent an innovative class of numerical methods designed to address the challenges posed by stiff differential equations. By incorporating the matrix exponential to treat ...

We introduce a new class of exponential integrators for the numerical integration of large-scale systems of stiff differential equations. These so-called Rosenbrock-type methods linearize the flow in ...

This paper provides a numerical technique for determining the parameters in a model expressible as the sum of exponentials. The essence of the method is to rewrite the model so that after ...
