Abstract: | This paper describes a corrector Crank-Nicolson numerical method for solving the heat equation,and its different scheme is explicit formulation. We prove that the proposed method is conditionally stable when r≤3. Numerical experiment shows that this method is accurate and it can be used directly on computers. |
