FISHPACK - A Poisson Equation Solver This is called Laplace's equation. For a domain Ω ⊂ R n with boundary ∂ Ω = Γ D ∪ Γ P, the Poisson equation with particular boundary conditions reads: − ∇ ⋅ ( ∇ u) = f i n Ω, u = 0 o n Γ . It is inherited from the of generic methods as an instance of the rv_discrete class. The issue appears at wavenumber k = 0 when I want to get inverse Laplacian which means division by zero. The Poisson distribution is the limit of the binomial distribution for large N. Note New code should use the poisson method of a default_rng() instance instead; please see the Quick Start . It completes the methods with details specific for this particular distribution.
