Computing the Gram Matrix for a set of Spline Basis

Functions to generate a Hankel matrix.

1 |

`x` |
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) |

Computes a Hankel matrix. If we denote the vector *x=(x_1,…,x_n)* the Hankel matrix is defined and formed as

*A matrix where each antidiagonal of the matrix is constant.*

a matrix as defined above.
