Web28 de ago. de 2024 · The choice of an appropriate spectral method should be defined by the two main considerations: the accuracy and the efficiency. In order to be useful a spectral method should be designed to give results of greater accuracy than can be obtained by more conventional difference methods using similar spatial resolution or … Spectral methods are a class of techniques used in applied mathematics and scientific computing to numerically solve certain differential equations. The idea is to write the solution of the differential equation as a sum of certain "basis functions" (for example, as a Fourier series which is a sum of sinusoids) and then to choose the coefficients in the sum in order to satisfy the differential equation as well as possible.
