numeric vector to specify the entries of the matrix. Should have an even number of entries.
nrow
integer, must be at most length(x)
ncol
integer, must be at most length(x)
Value
a matrix as defined above.
Details
Computes a Hankel matrix. If we denote the vector \(x=(x_1,\dots,x_n)\) the Hankel matrix is defined and formed as
$$H=\left(
\begin{array}{ccccc}
x_1&x_2&x_3&\cdots&x_{1/2}\\
x_2&x_3&&\vdots&\vdots\\
x_3&&\vdots&&\vdots\\
\vdots&\vdots&&&\vdots\\
x_{1/2}&\cdots&\cdots&\cdots&x_n
\end{array}\right).
