Calling local functions from command line
function-pointers, matlab, scope
Solution
The official documentation says that:
... you cannot call a local function from the command line or from functions in other files.
According to this, you must pass its handle to the caller in order to allow invoking it indirectly outside its m-file. I believe that there is no documented sensible way to access local functions otherwise.
Oddly though, you can still do this with `help`:
help public_function>local_function
Problem
I have a local function defined in an m-file. For example: ``` % begining of public_function.m file function fh = public_function( ) % % do some computation... fh = @local_function; % return function handle to local function defined below function y = local_function( x ) % % a local function inside public_function.m file % % some manipulation on x y = x; % end of public_function.m file NOTE THAT local_function is NOT nested ``` Now, I would like to call `local_function` from command line (and not from `public_function`). I was able to do so using the function handle returned from `public_function`: ``` >> fh = public_function(); % got handle to local_function >> y = fh( x ); % calling the local function from command line :-) ``` My question: Is there any other way (apart from explicitly pass the function handle) to call local function from command line (or other m-file/functions)? More precisely, I want a method to access any local function in a file (provided that I know its name). So, if I have `public_function.m` file (and function) and I know that `local_function` is local to that file, is there a way to access `local_function` from command line ?
