How to implement differentiation in C++

Hi,

I am trying to implement differentiation in C++. I have no clue on how
to do it. Could anybody suggest an algorithm or a refernce on where I
could find something on this topic.

Hi,

I am trying to implement differentiation in C++. I have no clue on how
to do it.

First, you need to be a little more clear about what kind of
differentiation. Do you want (a) numerical methods for computing the
derivative of a function? Do you want (b) symbolic differentiation of a
symbolic expression. If the latter, do you want that to happen at run-time
or do you want a (c) template based solution that makes it happen at
compile time.

Could anybody suggest an algorithm or a refernce on where I
could find something on this topic.

Depending on what you want, google for

(a) numeric differentiation.
(b) symbolic differentiation.
(c) expression templates differentiation.

Settle on a method and try putting it into code. When problems arise, come
back here with what you have and someone will be happy to help you
straightening out your code.
