Private Functions
Overview
Private functions are functions that reside in subfolders with
the special name private. These functions are called private because
they are visible only to functions and scripts that meet these conditions:
A function that calls a private function must be defined
in a program file that resides in the folder immediately above that private subfolder.
A script that calls a private function must itself
be called from a function that has access to the private function
according to the above rule.
For example, assume the folder newmath is
on the MATLAB search path. A subfolder of newmath called private can
contain functions that only the functions in newmath can
call.
Because private functions are invisible outside the parent folder,
they can use the same names as functions in other folders. This is
useful if you want to create your own version of a particular function
while retaining the original in another folder. Because MATLAB looks
for private functions before standard functions, it finds a private
function named test.m before a nonprivate program
file named test.m.
Primary functions and subfunctions can also be implemented as
private functions.

Private Folders
You can create your own private folders simply by creating subfolders
called private using the standard procedures for
creating folders on your computer. Do not place these private folders
on your path.

Accessing Help for a Private Function
You can write help for private functions using the same rules
that apply to primary functions. To display the help for a private
function, precede the private function name with private/.
For example, to get help on private function myprivfun,
type
help private/myprivfun
