D.3.2.25 jordannf
Procedure from library linalg.lib (see linalg_lib).
- Usage:
- jordannf(M); matrix M
- Assume:
- eigenvalues of M in basefield
- Return:
- matrix J; Jordan normal form 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);
==> 3,2,1,
==> 0,2,1,
==> 0,0,3
print(jordannf(M));
==> 2,0,0,
==> 0,3,0,
==> 0,1,3
