Procedure from library linalg.lib (see linalg_lib).

Usage:
jordanform(M); M constant square matrix

Assume:
The eigenvalues of M are in the coefficient field.

Return:
matrix, the Jordan normal form of M.

Note:
A non constant polynomial matrix M is replaced by its constant part.

Display:
The procedure displays more comments for higher printlevel.

Example:
 
LIB "linalg.lib";
ring R=0,x,dp;
