exist() for functions only?

As I understand, the exist() function in MATLAB will return "2" if the input is a MATLAB function.

The list of options for the second input 'kind' are builtin, class, dir, file, and var.

I want to input 'kind' so that exist() will ONLY search for functions, and return 2 if it is a match to a function and a 0 if not.

Is there any way to do this?

So you mean ONLY functions or any MATLAB files that will run (scripts/functions/classes)? which will return something for scripts and classes as well.

For functions only, this blog post and ensuing comments explains:

Answer 1

An option that is not exactly what you describe, but might work for you:

isempty(which([functionname,'.m']))

[per isakson]

... but why not just

    isempty(which( functionname ))

[matt dash]

Without the .m it will not distinguish between functions and variables.

[per isakson]

Yes, exactly!

Will this work in a deployed application? since the file isn't actually on the filepath any longer as its packaged in an EXE?

What about p-files?

Answer 2

exist()==2

%or

A = exist('name','file')

[Daniel]

My problem here is what if it exists as a workspace variable or another non-m file on the search path? in that case it will return 1 or 5 respectively, while I would still not be sure if it exists as a funciton.
