WebApr 7, 2016 · I am trying to solve the Viscous Burgers equation using the spectral method. u t + u u x = D u x x where D is a constant (chosen to be zero) and with the initial condition u ( x, 0) = e x p ( − x / 0.2) 2 I will use the spectral method for the spatial derivatives. f denotes Fourier transform. f ( u t + u u x) = D f ( u x x) WebApr 4, 2024 · One of the key concepts of spectral clustering is the graph Laplacian. Let us describe its construction 1: Let us assume we are given a data set of points X:= {x1,⋯,xn} ⊂ Rm X := { x 1, ⋯, x n } ⊂ R m. To this data set X X we associate a (weighted) graph G G which encodes how close the data points are. Concretely,
WebThis course provides you with a basic introduction how to apply methods like the finite-difference method, the pseudospectral method, the linear and spectral element method to the 1D (or 2D) scalar wave equation.
