Help text

 lyngby_nn_qddevds    - 2nd der., quadratic, input, diag gauss.

       function ddEV = lyngby_nn_qddevds(X, V, W, H12)

	Input:  X      Neural network input
               V      Input weights
               W      Output weights
               H12    (1-tanh(XV).^2) 

       Output: ddEV   Derivative in a matrix

       Diagonal Gauss-Newton (symmetric) approximation to the second
       order derivative of the qaudratic error function with respect
       to the input weights in the neural network.
