Lecture 6: How to multiply sparse matrices given in their triplet form?

In this tutorial I have discussed how we can multiply 2 sparse matrices given in their triplet form.

For watching my tutorial on Sparse matrix representation in Triplet and CSR form kindly refer to the following link:

For my tutorial on finding transpose of a sparse matrix in triplet form please refer to the following link:

I was really frustrated when I was trying to find a decent tutorial of sparse matrix operations, and this video truly SAVED MY LIFE! Thank you very much Professor!

Amazing! It helps me a lot for my C++ homework!

What's valuable about this tutorial is that it shows a practical application of this multiplication technique that I haven't seen in any other videos. What I think would help would have been to cover WHY this works (ie, by using the transpose of B). It would also be good to know how why spending the additional computing cycles to take the matrix provides benefit over simply doing a dot-product multiply. One other thing - I don't think the background music provides any benefit and is actually a quite distraction. But, thank you very much for providing this example.

Good presentation 👍

Carry on the good job 😊

You didn't sort the resultant matrix. It was written in the algorithm in the last step. BTW nicely explained.

[kdharshan]

on what basis is the transpose of that matrix B given? I am unable to make no sense of it. Please explain

How to transpose a matrix can you please tell it

[tejaswinizalki]

Mam, can u post video on program of sparse matrix representation, addition, multiplication???
In c++ program??

[deven]

idk how she made transpose of that matrix
