    Abstract: Laplace’s equation is one of the important equations in studying applied mathematics and engineering problems including the study of temperature distribution of steady-state heat conduction or the concentration distribution of steady-state diffusion problems. In this study, the analytical method has been applied to solve the Laplace's equation in a... Show More

    Abstract: Rapid evaluation of the Faddeyeva function, also known as the complex probability function, is essential to many spectroscopic and stellar applications. Humlíček’s W4 Algorithm is widely used in the literature for rapid and marginally accurate evaluation of the function (~10-4). However, as reported in the literature, the algorithm lose its claimed... Show More
