triDiagonal: Tridiagonal Matrix Functions

Description

Functions to create forms of tridiagonal matrix objects.

Usage

triDiag(diagonal, upper, lower, nrow = length(diagonal), ncol = nrow)
triDiag2(diagonal, upper, lower, nrow = length(diagonal), ncol = nrow)
triDiag2S(diagonal, upper, lower, r = length(diagonal))
triDiag3(diagonal, upper, lower, nrow = length(diagonal), ncol = nrow)
triDiag3S(diagonal, upper, lower, r = length(diagonal))

Arguments

diagonal, upper, lower

Numeric data to store in these positions.

nrow, ncol

Number of rows and columns

r

size of square matrix

Value

Tridiagonal matrices, constructed by a variety of computations, as described in the book.
