I looked into this a bit ago and dropped it because of other deadlines, but
all I could find was a small routine on Statlib,
It's not pretty and doesn't do ML for you, but maybe it's worth a start?

Maybe over the holidays I'll get around to writing up something original.
I've got a need to estimate the state evolution matrix in a big-dimensional
problem myself.  Of course, if you find anything that already works well...

Good Luck,
