Need to determine where function comments should be placed in MATLAB when abstract base classes are present

[elsevers]

When a class is implementing a base class, should the comments that describe its function be located in the abstract base class? Or in the class? I think it should be the abstract base class, but will MATLAB know to search there if someone types help?

Here is an example:

https://github.com/Severson-Group/eMach/blob/58f1f70dab76cf08dfeedd5f887436c983c8d4c8/tools/ToolBase.m#L15-L18

It looks like the comments should be located in the class. To verify this, I removed comments from the open function in MagNet tool, added comments to the ToolBase and did a help MagNet.open and also a help ToolBase.open.
That gave me this generic help about Matlab's inbuilt open function, and nothing from the ToolBase.

Here is what I see when I add the documentation in the MagNet tool
