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 ...

Exponential Integrators: Numerical methods that use the matrix exponential to integrate the linear part of a differential equation exactly, thereby mitigating stiffness-related challenges.

In this paper, we first establish a series representation formula for the Askey–Wilson operator applied on entire functions of exponential type and then demonstrate its power in discovering summation ...
