- Purpose of use
- transform 2-D singular integrals to singularity-canceled form, use Cartesian product of Gauss-Legendre rules for high precision integration for solving integral equations
- Comment/Request
- 1) Sign is incorrect in last equality, eq. (3) above. Weights would be negative!
2) Programmed the algorithm summarized above and found, for 34 sig. figs. at least, Newton's method more efficient than Halley's method! Not sure why, and perhaps not always true. . - from Keisan
- Thank you for your advice.
We modified the last equality, eq.(3).
