LAPLACE solves Laplace's equation in two dimensions, with Dirichlet
boundary conditions on arbitrary boundaries. LAPLACE calculates
the potentials on a rectangular equally spaced grid of W * H points
ranging from XMIN to XMAX and from YMIN to YMAX. The user may
use switch options to initialize these six parameters. C source
code is included.
This is one of two programs (the other program is an accounting
program) contained in the PC/Blue Library, compiled and distributed
by the New York Amateur Computer Club, Inc, Box 3442, Church St
Station, New York, NY 10008.
