This function calls the cost function and makes it match neldermead
requirements. It is used in the `fminbnd`

function as the
`function`

element of the neldermead object (see `?neldermead`

and `?neldermead.set`

).

1 | ```
fminbnd.function(x = NULL, index = NULL, fmsfundata = NULL)
``` |

`x` |
A single column vector of parameter estimates. |

`index` |
An integer variable set to 2, indicating that only the cost function is to be computed by the algorithm. |

`fmsfundata` |
An object of class 'optimbase.functionargs' and with
(at least) a |

Returns a list with the following elements:

- f
The value of the cost function at the current point estimate.

- index
The same

`index`

variable.- this
A list with a single element

`costargument`

which contains`fmsfundata`
