I use Excel to model a chemical process.
In order to do optimization search I need to find the (partial
derivatives (first and second) of certain cells with respect to othe
cells.
Without having to take the analytical derivative (which may be ver
time consuming as some of the formulae are very complex) has anyon
developed a function to calculate the numerical derivative
