Hello @eriknw, thanks for your help with pointing me to the .ss namespace for methods such as flatten() and reshape().
I have since found some implementations examples in your unit-test located here: ./graphblas/tests/test_matrix.py:. It seems to cover exactly what we are looking for and appears to work the same as scipy.sparse. There is even support for Fortran order flattening :).
I was simply wondering if we could reflect some of these methods in the docs? And perhaps expand a bit more on the .ss namespace? The only place where I could find mentions of the namespace is here. And the API reference doesn't seem to cover the namespace either.

   You bet! Glad they work.

   And I agree that it would be great if these were documented on the docs website. Any chance I could talk you into making a PR? ;) I'd be happy to answer questions and help out as I'm able.

   Yes, I'd be happy to make PR.
   I was wondering also, how can we adjust the suite-sparse settings? For example, we are considering defaulting to using csc matrices instead of csr.

   Awesome ❤️ !

   I was wondering also, how can we adjust the suite-sparse settings? For example, we are considering defaulting to using csc matrices instead of csr.

   To change default orientation (which is rowwise), do:

   gb.ss.config["format"] = "by_col"

   To change the orientation of a single Matrix, do:

   A.ss.config["format"] = "by_col"

   To see details of the config options, I usually look in IPython via gb.ss.config? or A.ss.config? or e.g. help(gb.ss.config).
