请教：如何构造hankel矩阵

luyunjun023

比如我有一列数据或几列数据，我想构造一个hankel矩阵怎么做，我想问的是如何控制hankel矩阵的维数。
不是直接hankel一下了事。

Hankel matrix

Syntax

H = hankel(c)
H = hankel(c,r)



Description


H = hankel(c) returns the square Hankel matrix whose first column is c and whose elements are zero below the first anti-diagonal.

H = hankel(c,r) returns a Hankel matrix whose first column is c and whose last row is r. If the last element of c differs from the first element of r, the last element of c prevails.

Definition


A Hankel matrix is a matrix that is symmetric and constant across the anti-diagonals, and has elements h(i,j) = p(i+j-1), where vector p = [c r(2:end)] completely determines the Hankel matrix.

Examples


A Hankel matrix with anti-diagonal disagreement is
c = 1:3; r = 7:10;
h = hankel(c,r)
h =
    1    2    3    8
    2    3    8    9
    3    8    9   10

p = [1 2 3 8 9 10]

谢谢你！
这个我看了，关键是还是不懂。
比如：我有3列数据，想用这三列构造一个hankel矩阵，怎么控制维数，主要是列数控制，比如我需要构造为10列的hankel矩阵。
直接hankel的话，hankel矩阵的行数=列数=原矩阵的行数*列数
