Undefined function or method '...' for input arguments of type 'double'.

I'm getting the following error when I try to run some function m-files: ??? Undefined function or method '[name of function]' for input arguments of type 'double'.

I know this usually happens when the file isn't in the working directory, but that's not the case here.

When I was running these m-files in a different directory on my computer, it worked fine. I moved them to another directory on my laptop, and they're still fine, but I get this error on two of my desktops.

Thank you.

Answer 1

Are you function names in mixed case, and your laptop runs Windows but your desktop runs Linux ?

Yes, the function names are mixed case.

The laptop and one of the desktops run Windows 7.
The other one is a Mac.

I get the same errors on both desktops, though.

Answer 2

change the working directory to the folder where you have your code or add the path.

Go to the File and choose the Set Path

That's not the problem. The file is in the working directory.

I've tried running it from the editor, but I'm getting the same error.

You have to add the path

Hi,

Please consider that you should be EXACTLY in the same directory; and not even in sub-directories within the right path.

I hope this solves the case. It worked for me.
