Return codes #4

Do we use GrB_Info or have LAGr_Info that contains (possibly) a GrB_Info and a much richer set of information.

Is there an LAGr_error() that does analogous tasks to GrB_error() or something completely different.

ScottKolo commented 4 years ago

Given the discussion in #6, if we go with LAGr_Matrix, we should probably go with LAGr_Info.

As you've pointed out, we can include algorithm-specific error messages and other LAGraph-specific functionality. I think this would be particularly useful given that the LAGr_Matrix being discussed is not opaque, and so we may need to notify the user of a lot more possible errors (e.g. "Hey, you told me this matrix was symmetric and it's not!").

I agree with you …. LAGr_info rather than GrB_info.

I really hope that LAGraph is successful as a standalone library and that most of our users will not really know (or care) that GraphBLAS is running behind the scenes.
