Details

The main functions are

grad	  to calculate the gradient (first derivative) of a scalar 
  	  real valued function (possibly applied to all elements 
  	  of a vector argument).

jacobian to calculate the gradient of a real m-vector valued function with real n-vector argument.

hessian to calculate the Hessian (second derivative) of a scalar real valued function with real n-vector argument.

genD to calculate the gradient and second derivative of a real m-vector valued function with real n-vector argument.
