请教：如何构造hankel矩阵
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
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 = 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 = 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
