| 0 | 1 % Start with all matrix returns. When that works see how we should generalize to non-matrix stuff/nonlinear |
| 2 classdef Scheme < handle | |
| 3 properties (Abstract) | |
| 4 m % Number of points in each direction, possibly a vector | |
| 5 order % Order accuracy for the approximation | |
| 6 | |
| 7 % vectors u,v,w depending on dim that gives were gridpoints are in each dimension | |
| 8 % vectors x,y,z containing the x,y,z values corresponding to each grid point | |
| 9 % matrices X,Y,Z with point coordinates as multi dimensional vectors | |
| 10 | |
| 11 D % non-stabalized scheme operator | |
| 12 H % Discrete norm | |
| 13 | |
| 14 % Should also containg: | |
| 15 % the grid points used | |
| 16 % the grid spacing | |
| 17 end | |

| 19 methods (Abstract) | |
| 20 % Closure functions return the opertors applied to the own doamin to close the boundary | |
| 21 % Penalty functions return the opertors to force the solution. In the case of an interface it returns the operator applied to the other doamin. | |
| 22 % boundary is a string specifying the boundary e.g. 'l','r' or 'e','w','n','s'. | |
| 23 % type is a string specifying the type of boundary condition if there are several. | |
| 24 % neighbour_scheme is an instance of Scheme that should be interfaced to. | |
| 25 % neighbour_boundary is a string specifying which boundary to interface to. | |
