WebUnfortunately, the matrix A would have lost its Hankel structure. We want to find a Hankel matrix H that will be “close” to A. Hankel Matrix Approximation. Given a (k +1)×l matrix A of rank-r, find a (k +1)×l Hankel matrix H of rank-r such that kA −Hk F = min. A simple way to get a Hankel structure from A is to average along the an- WebH = hankel (c) H = hankel (c,r) Description example H = hankel (c) returns a square Hankel Matrix where c defines the first column of the matrix, and the elements are zero below the main anti-diagonal. example H = hankel (c,r) returns a Hankel matrix with c as its first column and r as its last row.
