tridiag: Tridiagonal matrix

In EfficientMaxEigenpair: Efficient Initials for Computing the Maximal Eigenpair

Description

Generate tridiagonal matrix Q based on three input vectors.

Usage

tridiag(upper, lower, main)

Arguments

upper	The upper diagonal vector.
lower	The lower diagonal vector.
main	The main diagonal vector.

Value

A tridiagonal matrix is returned.

Examples

a = c(1:7)^2
b = c(1:7)^2
c = -c(1:8)^2
