# netderiv

## Purpose

Evaluate derivatives of network outputs by weights generically.

## Synopsis

    g = netderiv(w, net, x)

## Description

`g = netderiv(w, net, x)` takes a weight vector `w` and a network data structure `net`, together with the matrix `x` of input vectors, and returns the gradient of the outputs with respect to the weights evaluated at `w`.
