- 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:

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!
Glad it helped!
Amazing! It helps me a lot for my C++ homework!
Teşekkürler hintli apla 🤠
Amazing..!!!👍🏻👍🏻
Good presentation 👍
Carry on the good job 😊
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.
Firstly, I would like to thank you for viewing my tutorial and giving me a positive feedback. I guess I can make a tutorial on WHY this works, but that would be more of a mathematical approach. I think I can cover it when I make tutorials on Design and Analysis of Algorithms. I also agree with you regarding the background music. Actually its more of a beginners mistake in making video tutorials :-) I have learned from my mistake and have skipped adding any music to my recent videos. Hope you will enjoy them too. :-)
nicelyy explained
You didn't sort the resultant matrix. It was written in the algorithm in the last step. BTW nicely explained.
on what basis is the transpose of that matrix B given? I am unable to make no sense of it. Please explain
Just reverse rows and columns and arrange them in increasing order of rows
Mam, can u post video on program of sparse matrix representation, addition, multiplication???
In c++ program??
Sure I will...
How to transpose a matrix can you please tell it

idk how she made transpose of that matrix
Why take the transpose?
Because when you perform matrix multiplication, you multiply rows of the first matrix to the column of the second matrix...Here everything is enetered row-wise...hence transpose
