TOEPSOL Function
Solves symmetric Toeplitz linear equations using Levinson’s algorithm.
Usage
result = TOEPSOL(r, b)
Input Parameters
r—The first row of the Toeplitz matrix.
b—The right-hand side of a linear equation.
Returned Value
result—An array containing the solution of the linear equation.
Keywords
None.
Discussion
Given the first row of the Toeplitz matrix:
and the right hand side array b = [b(0), b(1), ..., b(m)]T, TOEPSOL is a fast algorithm for solving the linear equation
Rx = b
for the array x.
 
note
TOEPSOL is for symmetric, positive, definite matrices only.
Example
TOEPSOL is one of a suite of functions (JURYRC,  LEVCORR, LEVDURB, and TOEPSOL) used to solve Toeplitz linear equations and factorization problems. For an example demonstrating the use of TOEPSOL, see the description of JURYRC (JURYRC Procedure).
