some more on the current status of the documentation of classes:
The __call__ method also seems to be a second class citizen, not only
in interpolate. I assume it is not automatically included in the
autodoc. I just checked scipy.stats.rv_continuous and
stats.kde.gaussian_kde. rv_continuous mentions the __call__ method in
the class docstring, but there is no further reference,
stats.kde.gaussian_kde is silent about it's __call__ methods
Also the class docstrings don't link to or list the methods. For
example rv_continuous lists all the important methods but there are no
Additional to the classes in scipy, I checked numpy.DataSource and
numpy.random.RandomState, and the help page for them is pretty
uninformative, I don't know and cannot link to any of their methods.
compare this for example with help(numpy.DataSource)
I hope that by the end of this years gsoc, we will be adding many
stats.model classes. So a good documentation pattern for classes would
be very helpful for us. And if we allow for different array subclasses
in the __init__ method, then we need the facility to document them. A
similar example is scipy.signal.lti which allows 3 different
constructors, see the doc page at
I don't know whether this just needs some additional rst files,
changes in the automatic document creation or in the docstring
Of course there is the way of writing full rst docs as in
but that looks like a lot of additional work, which might not happen
So I think that for small to medium sized classes we should find a way
to create automatic class documentation including special methods
__init__ and __call__ and maybe others, if these methods have a
special meaning. __init__ is useful if we want to describe the
constructor in more detail instead of copying all information into the
class docs or to separate rst files.
I'm still stuck getting members or methods added to an autoclass
