Functions

Solves a linear system where the matrix is square tri-diagonal. That is, given a system of equations:

A * result = vecRight,

this class computes result = inv(A) * vecRight, where A has the special form of a tri-diagonal matrix:

|dia(0) sup(0)   0    0     ...   0|
|sub(0) dia(1) sup(1) 0     ...   0|

A =| ... | |0 ... 0 sub(n-2) dia(n-1) sup(n-1)| |0 ... 0 0 sub(n-1) dia(n)|

Parameters

`subDiag`	`Array<number>`
	The sub diagonal of the matrix.
`mainDiag`	`Array<number>`
	The main diagonal of the matrix.
`supDiag`	`Array<number>`
	The super diagonal of the matrix.
`vecRight`	`Array<number>`
	The right vector of the system of equations.
`opt_result`	`(Array<number>\|null)=`
	The optional array to store the result.

Returns

Array<number>

The vector that is the solution to the system.
