# Table 8 The number of iterations, execution times (in sec) and errors of C–N high-order finite difference method for Test problem 1, when \(\gamma =0.1\)

Theory and Modern Applications

| Iteration | Time | Maximum error | Average error |
---|---|---|---|---|

\(h=\tau =\frac{1}{10}\) | 52 | 18.42 | 5.7562 × 10 | 2.7256 × 10 |

\(h=\tau =\frac{1}{18}\) | 49 | 216.68 | 4.6550 × 10 | 2.1446 × 10 |

\(h=\tau =\frac{1}{22}\) | 56 | 601.96 | 4.0416 × 10 | 1.8512 × 10 |

\(h=\tau =\frac{1}{30}\) | 63 | 2577.19 | 3.0746 × 10 | 1.4077 × 10 |
