training adaline neuron w "trainwh"

Hi there,
I'm hoping someone with the neural networks toolbox (and a little
more knowledge than me) can answer a few questions.

1) the neural netork toolbox manual says that the trainwh function
uses the "Widrow Hoff" learning algorithm. I cant find any direct
references to that in Widrow's "Adaptive signal processing" book.
Is the Widrow Hoff LR the same as the Least Mean Squares

2) The trainwh function returns a bias value. The lms algorithm
doesn't address adjustment of the bias input - what rule does this
function use for bias adjustment?

3) I thougth that the lms algorithm was supposed to "jitter about"
when it gets close to the minimum error (i.e. the best set of
synaptic weights) when I run the training algorithm I get what
appears to be an exponential decrease in the error function over
time. What is going on?
