This is a collection of programs for solving a boundary integral equation
reformulation of the interior Dirichlet problems for Laplace's equation in *R*^{3}.
The programs are described in the paper

K. Atkinson, Algorithm 629: An
integral equation program for Laplace's equation in three dimensions, *ACM
Transactions on Mathematical Software* **11** (1985), pp. 85-96.

Generalizations
have been written for other boundary integral equation problems, and the author
should be contacted directly for information about these programs, at
Kendall-Atkinson@uiowa.edu.

You can access a general
introduction,
the program
*gnrt.f*
(to generate the Galerkin coefficients), and the program
*dirichlet_3d.f
* (to solve the interior Dirichlet problem).

Auxilliary files and programs of interest:

- input_file_name, giving the same of the file containing the data.
- gnrt.data,
giving actual data for running the program
*gnrt.f*. - gnrt.data-model,
giving the format of the data file for running the program
*gnrt.f*. - print_coeff.f,
a utility program to print in a readable fashion the spherical polynomial
coefficients generated by
*gnrt.f*. - basis_num.f,
a utility to generate the indices of the various coefficients in a more common
format, translating from the format used in
*gnrt.f*and*dirichlet_3d.f*. - dirichlet.datagiving
actual data for running the program
*dirichlet_3d.f*. - dirichlet.data-model,
giving the format of the data file for running the program
*dirichlet_3d.f*.
