Preconditioners constructed from the interpolative decomposition for the variable coefficient Poisson problem
When trying to solve elliptical problems such as the Poisson problem on complicated domains, one procedure is to split the domain into a union of simpler subdomains. When solving these problems iteratively, it becomes important to be able to precondition the coupling between the subdomains. Using …
