Detailed Description

Matrix entries for a mass balance 5/7/9 star system.

Matrix entries for the mass balance of a 5 star system

The entries are center, east, west, north, south and the right side vector b of Ax = b. This system is typically used in 2d.

Matrix entries for the mass balance of a 7 star system

The entries are center, east, west, north, south, top, bottom and the right side vector b of Ax = b. This system is typically used in 3d.

Matrix entries for the mass balance of a 9 star system

The entries are center, east, west, north, south, north-east, south-east, north-wast, south-west and the right side vector b of Ax = b. This system is typically used in 2d.

Matrix entries for the mass balance of a 27 star system

The entries are center, east, west, north, south, north-east, south-east, north-wast, south-west, same for top and bottom and the right side vector b of Ax = b. This system is typically used in 2d.
