Sparse Matrices - Intro to Parallel Programming 

The last element in the column vector of CSR representation should be a 2 instead of 1.

Very good explanation! It would've been useful to also see how to reconstruct the matrix from the three arrays.

How would I reconstruct a matrix from the three things in a case where a whole row is 0

The array of value should be notified as in the order as exact listed, if not, when reconstructing matrix, d could be in row 1 without any conflict to construct method

best explanation so far, thank you so much!! life savior

the method here is diffrent from other youtube videos where they have 3 col matrix, so when to use each method?

what about CSC

How do we construct the original matrix from the sparse matrix? Thanks

What about BSR

what if a row only has zero?

You sound like Bill Gates

This video seems rushed and it does not explain much. And has an error, as others pointed.
