get source file path of a library function
path = get_function_path(fun_name)
a string, the name of the function
a vector of strings containing:
"<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)[]
.Given the name of a function get_function_path returns a vector containing
"<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.
