hankel

Hankel matrix

Syntax

• H = hankel(c)

• H = hankel(c, r)

Input argument

• c - First column of Hankel matrix: vector or scalar.

• r - Last row of Hankel matrix: vector or scalar.

Output argument

• H - Hankel Matrix.

Description

H = hankel(c) returns a square Hankel Matrix with c the first column of the matrix and the elements are zero below the main anti-diagonal.

H = hankel(c, r) returns a Hankel matrix with c as its first column and r as its last row.

If last element of c differs from the first element of r, then Hankel issues a warning and uses the last element of c for the anti-diagonal.

Example

c = [1 2 3 4 5];
hankel(c)
