Another perfect lecture, finally we can understand such beautiful subject and not just memorize it like mindless robots. Thank you so much Ritvik, your our hero! Gratitude from Brazil

"I want to make sure to show you the actual applications..." God bless this man.

This a huge gem! I love all your videos, they’re always a beautiful mix of theory, applied, and visual examples. I also think they’re the perfect length as well as depth and breath of connected material covered. That’s a delicate balance most technical YouTube videos fail at and what makes yours special. 👍

Excellent! What you said in the intro is the exact reason why I found your video!

[akshaysahu]

Man, you should have been my math teacher at undergrad level. I would have scored more than what I actually did. Simple yet effective explanation.

[swenpai]

Best explanation I've seen about this subject! Thank you!

[prajwalchoudhary]

best explanation of rank of a matrix in the world and how it is related to data science

[jgianan]

You’re so gifted at explaining things in an easy to understand way! Thank you!

This is the best linear algebra explanation I've ever heard and I've watched basically everything. The only thing you missed was the geometric interpretation, the point of the basis axes don't change.

Still, absolutely excellent. 3b1b is the one everyone praises when actually he confuses simple things. You did the reverse.

I like the way you link these things with application, which is mind blowing...whenever I look for answer, I come here. thanks for all your videos.

I'm majoring Economics at South Korea. This video helped me so much. Thank you

PERFECT! As a programmer, I found the process just like "data normalization" which is indeed recommended and useful, amazing. One stupid question, so what's the difference between the column-column check you did, and echelon(row-row) form? I've seen some use echelon

4-5 years spent to understand the real world use case, that's so true brother, for many other concepts as well.

The explanation is really Awesome!!!
Thank you so much!!

[malaika-kh]

Thank you for making this so clear and specific!

[ozycozy]

This was the best, and filled many gaps in my mind, bravo👏

[ceremonious_houseplant]

Straight to the point and elegantly explained. Love it!

[kumarmukul]

Your explanation is awesome man. I simply love the way you explain the concept.
