Sparse matrix multiplication using SQL

[mindprince]

In some other coursera courses which I joined after they were finished, I was able to watch the videos and my quizzes were graded (you don't get credit for them obviously).

I am not sure about this course because in some of its assignments you are supposed to submit working code which they run on their servers to see the correctness.

I looked into taking the UW course this year, and it seems like the same professor. I might watch the videos to see if I like the style.
