Re: [R] algorithmic or automatic differentiation

No, computer algebra systems such as yacas do symbolic differentiation. Automatic differentiation is a numerical technique that can be used to find derivatives of functions that can be implemented as computer programs, through successive uses of the chain rule on the computer code itself. It would
