toeplitz.matrix: Toeplitz Matrix

In matrixcalc: Collection of Functions for Matrix Calculations

Toeplitz Matrix

Description

This function constructs an order n Toeplitz matrix from the values in the order 2 * n - 1 vector x.

Usage

toeplitz.matrix(n, x)

Arguments

n	a positive integer value for order of matrix greater than 1
x	a vector of values used to construct the matrix

Details

The element T[i,j] in the Toeplitz matrix is x[i-j+n].

Value

An order n matrix.

Note

If the argument n is not a positive integer, the function presents an error message and stops. If the length of x is not equal to 2 * n - 1, the function presents an error message and stops.
