R Documentation

Generate a tridiagonal matrix.

Description

Generate a tridiagonal matrix with upperDiag as superdiagonal, lowerDiag as subdiagonal and mainDiag as diagonal.

Usage

tridiag(mainDiag, upperDiag, lowerDiag)

Arguments

`mainDiag`	Diagonal of tridiagonal matrix.
`upperDiag`	Superdiagonal of tridiagonal matrix. Must have length `length(mainDiag) - 1`.
`lowerDiag`	Subdiagonal of tridiagonal matrix. Must have length `length(mainDiag) - 1`.

Value

Tridiagonal matrix.

Examples

set.seed(987)
mainDiag <- sample(100:110, size = 6, replace = TRUE)
upperDiag <- sample(10:20, size = 5, replace = TRUE)
lowerDiag <- sample(1:10, size = 5, replace = TRUE)

tridiag(mainDiag, upperDiag, lowerDiag)
