toeplitz — toeplitz matrix

Calling sequence

A=toeplitz(c [,r])

Parameters

a,c,r : constant, polynomial or string matrices

Description

returns the Toeplitz matrix whose first row is r and first column is c. c(1) must be equal to r(1). toeplitz(c) returns the symmetric Toeplitz matrix.

Examples



A=toeplitz(1:5);
//
T=toeplitz(1:5,1:2:7);T1=[1 3 5 7;2 1 3 5;3 2 1 3;4 3 2 1;5 4 3 2];
T-T1
//
s=poly(0,'s');
t=toeplitz([s,s+1,s^2,1-s]);
t1=[s,1+s,s*s,1-s;1+s,s,1+s,s*s;s*s,1+s,s,1+s;1-s,s*s,1+s,s]
t-t1
//
t=toeplitz(['1','2','3','4']);
t1=['1','2','3','4';'2','1','2','3';'3','2','1','2';'4','3','2','1']
