HANKEL

 

 Hankel matrix.

  HANKEL(C) is a square Hankel matrix whose first column is C and

  whose elements are zero below the first anti-diagonal.

  HANKEL(C,R) is a Hankel matrix whose first column is C and whose

  last row is R.

  Hankel matrices are symmetric, constant across the anti-diagonals,

  and have elements H(i,j) = R(i+j-1).
