# Laplace

Solves the Laplace equation `u_xx + u_yy = 0`

in a rectangular domain, by iteratively applying a stencil function function.

The first argument is the number of iterations to use. The second is a BMP file containing boundary conditions.

## Code

The main algorithm is at http://code.haskell.org/repa/repa-stable/repa-examples/Laplace/src/Solver.hs

The wrapper is at http://code.haskell.org/repa/repa-stable/repa-examples/Laplace/src/Main.hs

## Test Data

In the input file, greyscale gives the boundary conditions, blue is where to determine the solution.
