| Abstract: |
| In this paper, a bidirectional method for the numerical conformal mapping of exterior domain is proposed. The LSQR (least square QR-factorization method) is used to solve the approximate inverse conformal mapping of the constraint equations. The maximum modulus theorem for regular function can be used to estimate error. Numerical examples are presented to illustrate the efficiency of the method. |
