SciChart.Charting Assembly > SciChart.Charting.Model.Filters.SplineInterpolationFilter Namespace : TriDiagonalMatrixF Class |

A tri-diagonal matrix has non-zero entries only on the main diagonal, the diagonal above the main (super), and the diagonal below the main (sub).

Syntax

[DefaultMember("Item")] public class TriDiagonalMatrixF

Remarks

This is based on the wikipedia article: http://en.wikipedia.org/wiki/Tridiagonal_matrix_algorithm

The entries in the matrix on a particular row are A[i], B[i], and C[i] where i is the row index. B is the main diagonal, and so for an NxN matrix B is length N and all elements are used. So for row 0, the first two values are B[0] and C[0]. And for row N-1, the last two values are A[N-1] and B[N-1]. That means that A[0] is not actually on the matrix and is therefore never used, and same with C[N-1].
