hankel_cholesky, a MATLAB code which computes the upper Cholesky factor of a symmetric positive definite (SPD) Hankel matrix H, that is, H = R' * R.
A Hankel matrix is a matrix which is constant along all antidiagonals. A schematic of a 5x5 symmetric Hankel matrix would be:
a b c d e b c d e f c d e f g d e f g h e f g h i
