Getting a function I downloaded online to run

Hey guys, I'm extremly new to programming, so be patient with me!

I downloaded this script: https://www.mathworks.com/matlabcentral/fileexchange/33616-integer-partitions

and put it in a certain folder on my desktop, then used the addpath tool to add a path to this folder. I opened up the file in MatLab and the script appeared in an "editor window".

Now, if I type in intpartition(4) the output should be {[1 1 1 1],[1 1 2],[1 3],[2 2],4}

But instead it's saying

Undefined function or variable 'intpartition'.

What is the problem here? Did the addpath not work correctly? I find this strange because I got another program, nsumk, to run just fine, and they are in the same folder.

Thanks!

First, use dir on the folder to be certain it actually appears there.

Second, see what:

which('intpartition.m')

returns.

>> which('intpartition.m')

'intpartition.m' not found.

I have the file in my folder called "research," and then another copy of it in a folder called "Programs" that is itself in the folder "research. I added both of these folders via addpath and getting the correct path from my command prompt window

Run the path command from a script or the Command Window. It will tell you if those directories are part of the path. Your user file path components will be at the end of that list. (At least that applies to R2020b.)

[John D'Errico]

If you added the folders using addpath, verify you did it properly. path will tell you that. And then, make sure you SAVED the path, so it will be there next time.
