## Add to RxODE's derivative tables

### Description

Add to RxODE's derivative tables

### Usage

    rxD(name, derivatives)

### Arguments

`name` | Function Name
`derivatives` | A list of functions. Each function takes the same number of arguments as the original function. The first function will construct the derivative with respect to the first argument; The second function will construct the derivitive with respect to the second argument, and so on.

### Value

nothing

### Author(s)

Matthew Fidler

### Examples

    ## Add an arbitrary list of derivative functions
    ## In this case the fun(x,y) is assumed to be 0.5*x^2+0.5*y^2

    rxD("fun", list(
      function(x, y) {
        return(x)
      },
      function(x, y) {
        return(y)
      }
