[x] The L^B ones for the uniform won't change much, but maybe try one with decomposing into a sum of a matrix and a fudge. (Resolved by 63f2d6e)
How to denote the fudge matrix?
diag([fudge! {M-2} fudge!)]
[x] (Maybe) Apply it on irregular grids as well (Resolved by cc28b81)
[x] Type in (78) to (80 missing a delta. (Resolved by 151c1b6)
Get to section 4
[x] Review the structure of section 3 and reorganize section. i.e. discretize operators, then boundary conditions, then applying boundary conditions to operators.
[x] Equation (85) to (87) represent these as banded matrices. i.e. (90 to 92) are banded. (Resolved in 4aa9e02)
[x] Get rid of the I in (89) and (93). We already have that L_0 defined seprately. (Resolved by d2b4d7e)
[x] Continue on the boundary conditions (on their own) in a section (Resolved by 2b38f4f)
[x] When you do the application of the boundary conditions, careful to map things into (1) banded matrices and (2) decompose into the sum of a tridiag + a fudge
