 Post subject: Rational Canonical Form
PostPosted: Thu Aug 11, 2005 5:32 pm 
I want to compute the rational canonical form of a square matrix over a finite field. Based on what is in the library linalg, it seems that there is no built-in command for that.
Do you know how to compute RCF in Singular?
Any help will greatly be appreciated.

Thanks in advance.
Abdul

Actually, in the SINGULAR book there is an exercise 2.6.3 on the page 165, where a "rational normal form" is asked to compute.
There are hints to this exercise, so it is not complicated to implement it by yourself.
