...imal polynomial of a square matrix A (over the field of complex numbers)? I don't know whether this would require symbolic computation. If not, has any of the algorithms been implemented in R? Thanks very much, Ravi. P.S. Just for the sake of completeness, a minimal polynomial is a monic polynomial (whose leading coefficient is unity) of least degree, which divides all the annihilating polynomial of A. In particular, the minimal polynomial divides the characteristic polynomial. Knowing the degree of the minimal polynomial is useful in characterizing the convergence properties of a...

I rebased my previous 3 patches to the current master with minor changes. Patches 1 to 3 replace all my previous submitted patches. Patches 4 and 5 are new. Thanks, Linfeng Zhang
