wolffd@0: Description wolffd@0:

wolffd@0: wolffd@0:

hesschek(net, x, t) takes a network data structure net, together wolffd@0: with input and target data matrices x and t, and compares wolffd@0: the evaluation of the Hessian matrix using the function nethess wolffd@0: and using central differences with the function neterr. wolffd@0: wolffd@0:

The optional return value h is the Hessian computed using wolffd@0: nethess. wolffd@0: wolffd@0:
