Unfortunately, for technical reasonreasons it is usually not possible to split our grid of 64 points (a 64×64 system of linear equations) into two grids of 32 points (two 32×32 systems of linear equations) and obtain an answer to the 64×64 system. Instead, the following algorithm is what actually happens:
 
:1) Begin with an approximate solution of the 64×64 system.
