get_function_path get source file path of a library function

## Syntax

    path = get_function_path(fun_name)

## Arguments

fun_name

  a string, the name of the function

path

  a vector of strings containing:

  - absolute pathname of the function source file (.sci)
  - `"<script>"` if `fun_name` is an user-defined function written in Scilab language executed in Scilab's console.
  - `"<moduleName>"` if `fun_name` is a builtin function (so-called Scilab primitive)
  - Otherwise: `[]`.

## Description

Given the name of a function get_function_path returns a vector containing

- the absolute pathname of the function source file if the function is defined in a Scilab library (see lib)
- `"<script>"` if the function is an user-defined function executed in the console
- `"<moduleName>"` if the function is a builtin written and compiled in an external language (C, C++..)

get_function_path returns [] if `fun_name` does not match any library function.

## Examples

    get_function_path('median')
