Description
            This toolbox provides forward automatic differentiation. It is based on
operators and functions overloading.

Given a Scilab code computing a variable y depending on a variable x and a
direction dx it allow evaluation of y together with the directional derivative
Grad(y)*dx.

The module supports common arithmetic operations, common elementary functions
and several matrix functions, including matrix inversion.

Features
--------

The following is a list of the current functions :
 * diffcode_der -  Create a new code differentiation object.
 * diffcode_CDcost -  Objective function for optim.
 * diffcode_hessian — Compute the Hessian of the function.
 * diffcode_jacobian — Compute the Jacobian of the function.
