**Syntax**

**Description**

A *Toeplitz* matrix is defined by one row and one column. A *symmetric Toeplitz* matrix is defined by just one row. `toeplitz`

generates Toeplitz matrices given just the row or row and column description.

```
T = toeplitz(c,r)
```

returns a nonsymmetric Toeplitz matrix `T`

having `c`

as its first column and `r`

as its first row. If the first elements of `c`

and `r`

are different, a message is printed and the column element is used.

```
T = toeplitz(r)
```

returns the symmetric or Hermitian Toeplitz matrix formed from vector `r`

, where `r`

defines the first row of the matrix.

**Examples**

A Toeplitz matrix with diagonal disagreement is

c = [1 2 3 4 5]; r = [1.5 2.5 3.5 4.5 5.5]; toeplitz(c,r) Column wins diagonal conflict: ans = 1.000 2.500 3.500 4.500 5.500 2.000 1.000 2.500 3.500 4.500 3.000 2.000 1.000 2.500 3.500 4.000 3.000 2.000 1.000 2.500 5.000 4.000 3.000 2.000 1.000
