A New Method for Elliptic Partial Differential Equations

The study proposes a matrix method based on collocation points and Taylor polynomials for approximating the solution of elliptic partial differential equations. This method reduces the problem to solving a matrix equation with unknown Taylor coefficients, which are determined using the collocation points. The solution is then expressed in terms of Taylor polynomials. The technique is illustrated using a descriptive example, and the results are compared with a table and figure. The numerical calculations are performed using a program written in WOLFRAM MATHEMATICA 13.0.
