摘要內容：Abstract. In this talk, we introduce pseudospectral methods based on Legendre polynomials and Chebyshev polynomials. We present a novel approach for solving Poisson equations with variable coefficients. The algorithm is interpreted as a discrete analog of solving differential equations by integration.
Finally we present some numerical examples to show that the new approach avoids ill conditioning issues of solving Poisson equations.
