g = mlpderiv(net, x)
takes a network data structure net
wolffd@0: and a matrix of input vectors x
and returns a three-index matrix
wolffd@0: g
whose i
, j
, k
element contains the
wolffd@0: derivative of network output k
with respect to weight or bias
wolffd@0: parameter j
for input pattern i
. The ordering of the
wolffd@0: weight and bias parameters is defined by mlpunpak
