//Example of how to use the hank macro for 
 
48
//building a Hankel matrix from multidimensional 
 
49
//data (covariance or Markov parameters e.g.)
 
50
//
 
51
//This is used e.g. in the solution of normal equations
 
52
//by classical identification methods (Instrumental Variables e.g.)
 
53
//
 
54
//1)let's generate the multidimensional data under the form :
 
55
//  C=[c_0 c_1 c_2 .... c_n]
 
56
//where each bloc c_k is a d-dimensional matrix (e.g. the k-th correlation 
 
57
//of a d-dimensional stochastic process X(t) [c_k = E(X(t) X'(t+k)], ' 
 
58
//being the transposition in scilab)
 
59
//
 
60
//we take here d=2 and n=64
 
61
//
 
62
c=rand(2,2*64)
 
63
//
 
64
//generate the hankel matrix H (with 4 bloc-rows and 5 bloc-columns)
 
65
//from the data in c
