|  |  D.3.2.22 jordan Procedure from librarylinalg.lib(see  linalg_lib).
 
Example:Usage:
jordan(M); matrix M
Assume:
eigenvalues of M in basefield
Return:
|  | list l;  Jordan data of M
  ideal l[1];
    number l[1][i];  eigenvalue of i-th Jordan block of M
  intvec l[2];
    int l[2][i];  size of i-th Jordan block of M
  intvec l[3];
    int l[3][i];  multiplicity of i-th Jordan block of M

 |  | LIB "linalg.lib";
ring R=0,x,dp;
matrix M[3][3]=3,2,1,0,2,1,0,0,3;
print(M);
==> 3,2,1,
==> 0,2,1,
==> 0,0,3 
jordan(M);
==> [1]:
==>    _[1]=2
==>    _[2]=3
==> [2]:
==>    1,2
==> [3]:
==>    1,1
