D.3.2.20 minipoly
.................
Procedure from library linalg.lib (see linalg_lib).

Usage:
minpoly(M); matrix M

Assume:
eigenvalues of M in basefield

Return:
list l;  minimal polynomial of M
  ideal l[1]; 
    number l[1][i];  i-th root of minimal polynomial of M
  intvec l[2]; 
    int l[2][i];  multiplicity of i-th root of minimal polynomial of M

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