## Abstract This article is concerned with the numerical solution of Poisson's equation with Dirichlet boundary conditions, defined on the unit square, discretized by Hermite collocation with uniform mesh. In [1], it was demonstrated that the Bi‐CGSTAB method of van der Vorst [2] with block Red‐Bla
