Elementary Linear Algebra: Echelon Form of a Matrix, Part 2

In this video we describe the algorithm for finding an echelon form or the unique reduced echelon form of a matrix. This is the second video in a 3-part series.

I have tried every single video out there to understand this algorithm but no video has helped me. I don't know what you did, but it worked and I finally understand it. I cannot express how thankful I am right now, this video is no doubt the best explanation of the GJA Algorithm. Thank you again Sir!

The first non-zero entry of a *row* is called a pivot.

This was what I was looking for, Alnost 30 minutes ❤❤❤❤❤❤❤
Thank you 😊

[dawillygene]

I'm so thanksful for this wonderful tutorial ....Cant imagine the way am gonna beat this test

[DADDY]

THANks, really good video. Took the time to point out all the missteps a student might make. Definitely recommended.!

[pasinduminiruwan]

Thank you very much, sir. I'm a computer science student, I can't understand this when my lecturer teach this but after watching your video I understand how it works

[woolala]

the clearest one!!! I even didn't notice it was posted 8 years ago

[utkarshtripathi]

Sir I was struggling with echelon form.Your lecture made it clear.Thank u

How do matrices differ in Elementary Linear Algebra versus say Algebra II or College Algebra? i have never taken Elementary Linear Algebra but I do follow along with what your saying. I remember doing this stuff in Algebra II and College Algebra and did really well in it.

These videos are very well presented. You are really smart. Keep it going!

So easy illustration of all basic concept, I love this video in point of

[erickmorfin]

Wow.
Such a great video. You spoke very concisely. Thanks.

[k.e.l.obeats]

hello how are you? I think it would be better if you had shown the swapping and multiplication of the rows rather than just saying out the words.

[brainydolphinit]

Thank you sir.
This vedio is very helpful for my academic study💙💙

[averyriester]

Thank you so much this will probably be why I (hopefully) pass my test today

[tawseef]

thanks a lot for this series...it is very helpfull...

[bmariani]

Finally the SWAP rule is shown in action. Everyother video always manages to avoid doing this step

with gratitude appreciation. ..I thank you for your help
