- No, but MathWorks sells a Neural Networks Toolbox, just out. I don't
- know the price. I saw it demonstrated a couple of months

- better or more detailed review than that :-)

- However, standard bp is pretty easy to code up, in my opinion.
- Forward activation is just matrix multiply, squash, matrix multiply,
- squash...
- and standard delta rule learning is
- compute delta, update weights, back prop (matrix mult),
- compute delta, update weights, back prop...
