# neterr

## Purpose

Evaluate network error function for generic optimizers

## Synopsis

    e = neterr(w, net, x, t)
    [e, varargout] = neterr(w, net, x, t)

## Description

`e = neterr(w, net, x, t)` takes a weight vector `w` and a network data structure `net`, together with the matrix `x` of input vectors and the matrix `t` of target vectors, and returns the value of the error function evaluated at `w`.

`[e, varargout] = neterr(w, net, x, t)` also returns any additional return values from the error function.
