Daniel@0 25
Daniel@0 26 <p><CODE>hdv = mlphdotv(net, x, t, v)</CODE> takes an MLP network data structure
Daniel@0 27 <CODE>net</CODE>, together with the matrix <CODE>x</CODE> of input vectors, the
Daniel@0 28 matrix <CODE>t</CODE> of target vectors and an arbitrary row vector <CODE>v</CODE>
Daniel@0 29 whose length equals the number of parameters in the network, and
Daniel@0 30 returns the product of the data-dependent contribution to the Hessian
Daniel@0 31 matrix with <CODE>v</CODE>. The implementation is based on the R-propagation
Daniel@0 32 algorithm of Pearlmutter.
