From H = hankel(c) returns the square Hankel matrix whose first column is c and whose elements are zero below the first anti-diagonal. Examples of such matrices in&de Hankel striped, Hankel layered, and vector Hankel matrices. A. Sequence A000312/M3619 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. u�u���3�Tf������2 �.6�� �� ��m�*���=\��y��/�dAG�w��oU��@��j˳z~��N1ip�5n� ���\F�f/���Q���D>�8��B��:o--��+7�>��4��M���@2���]�a�,X? It is shown that the components that both determine nonsingularity and construct the inverse of such matrices are closely related to certain matrix polynomials. The Hankel matrix has constant anti-diagonals, with c as its first column and r as its last row. Such structure can be found in various fields, including subspace system identification (Fazel et al. example. ;��h/¤i��R��;m������-��nQ��JUp�}������vn� �6�|̄wΦ� We want to find a Hankel matrix H that will be “close” to A. Hankel Matrix Approximation. A square matrix with constant skew diagonals. The subscript k denotes results in the kth iteration, R : C (N+1)!C2N+1 is the adjoint operator of R, which transforms a Hankel matrix into a vector through summing each anti-diagonal. HankelMatrix[{c1, c2, ..., cn}] gives the Hankel matrix whose first column consists of elements c1, c2, .... HankelMatrix[{c1, c2, ..., cm}, {r1, r2, ..., rn}] gives the Hankel matrix with elements ci down the first column, and ri across the last row. The same result holds true if the word ‘Toeplitz’ is replaced by ‘Hankel,’ and the generic bound n/2+ 1 is sharp. Description. Theoretical analysis indicates that when the prior information is reliable, the proposed method has a better performance than vanilla Hankel matrix completion, which reduces the number of measurements by a logarithmic factor.
