I've spent more than an hour looking for some clean explanation about LU decomposition in my own language for my uni exam. After swearing... a little... and increasing my hatred towards my country I found your tutorial and you made me understand this whole thing in less than 6 minutes. Thank you!
Best video I have seen on this topic so far! I am lecturing an undergraduate math course this semester and you have just helped make it easier for me to explain the LU decomposition algorithm to my students. Thank you!
donbradman334 I should also point out just for interest that I am using a combination of your method and that in chapter 2.5 of Lay's linear algebra book to explain this to the students.
OMG this is the best explanation i could've found.You Successfully explained CLEARLY and SIMPLY the LU method whereas i've benn struggling for one month to understand the complicated lecture given by My teacher on this Topic at my Engineering School.Thank you so much Sir for the Great Job you've done .
I was a little confused when my instructor was teaching this. My textbook wasn't that clear either. Now, I understand it. Thanks for posting this video about how to do it.
I watched your video and it was self explanatory.I tried to watch another video to compare but I think you gave explanation to why the elements in the L matrix were so.Thank you sir.
Thank you so much. I think there is a need to make a revolution in university degree. TH-cam lessons are far more efficient than stupid useless 3 hour lectures.
Im wondering about this too... And are we only allowed to multiply one of the row only? Like is 2R1+3R2 allowed? if it is, which number should we plug onto the L? -2? -3? -2/3? -3/2? will all give the same answer?
Thank you both for your help in understanding the idea and for your providing of this practical method of implementation! Much more clear than university material... I just have one question...why does A need to be able to be reduced to U without row interchanges? Since this is also a row operation, that's not clear to me. Does this mean that, in practice, I cannot use techniques like Gauss pivoting to obtain U? Sorry but I am pretty much a beginner in this field...
Mate, i cannot stress how easy you have made this topic to comprehend. I am comfortable in this topic thanks to you!
That is great! Thank you for letting me know.
Mathispower4u Same here, Thank You!
I'm really so thankful to him, thanks ^_^
Thank you so much.
@@Mathispower4u Thank you!
I'm sorry but I watched every other videos about this topic but this guy taught it to me in less than 4 minutes...DAMN
Finally, a humanly appropriate tutorial on LU decomposition! Thank you!

Almost 8 years and i can't thank you enough, great job.
You're the man. I've been following you for 3 years now.
Thank you!
Is LU Decomposition the same as LU Factorization?
Yes
The best video on LU decomposition. Thank you
What took me hours to understand has just been demystified in 10min! You're amazing, I can't thank you enough!!!
Wow, you made this extremely easy to follow and comprehensive. I can't thank you enough!

THANK YOU!!!! I have spent hours on trying to figure this out and you made it easy to learn in 10 mins. Great video!!!
By far the best explanation I’ve watched. Thanks.
I've been watching your videos for a year and you saved my cal3 and linear algebra. Thank you!
You've helped me through all of my undergrad. THANK YOU.
this is by far the most concise and informative video of lu decomp. ive seen.
Thank you so much.

I can't believe how easy you made this lesson. All these other videos I watched just complicated my morning, but THANK YOU very much!
It felt like a pump of info before my quiz. Seems like you've been helping people like me for many years. You must have a vip place in heaven
I don't always comment but when i do, it is worth commenting. THIS IS BRILLIANT!!!
I couldn't understand this concept anywhere else before I saw this video. thank you so much!!
thx, nice explanation
Seriously thank you so much !!!! your explanations are clearer than a teacher with a PHD !!!
HOLY SHIT I'VE BEEN CRYING OVER NOT BEING ABLE TO DO THIS FOR 2 HOURS AND YOU JUST SAVED ME THANK YOU!
This is now infinitely easier to understand
You explained this 100x better than my instructor. Straight forward without meaningless definitions
Thank god someone other than my professor can teach this. You are helping me get a better grade on my final.
thank u thank thank u soooooo much after 11 years u are such a legend
Thank you for taking the time to leave a comment. I am glad I could help out. 😃
Great video. My university should be paying you to teach me, not my Numerical Analysis and Computing Professor. Thank you!
same, my numerical methods professor sucks
fra ti metterei mi piace ma cazzo stai a 69 non posso rovinarlo
this the best video I saw on TH-cam. I have been looking for hours.
Wow, thanks!
@@Mathispower4u Bro you alive??
@@ZEESHANALI-v4t Yes
I have a midterm in 3hrs and this was very helpful indeed. Other youtube videos were really confusing
Super method!!!
I was not able to solve LU decomposition till now.
This will help a lot.
Glad to know I could help!
Before seeing this video I was like "I'll never understand in my entire life" and after your explanations "it was easy af" ... thank u so much bro
I was a little confused when my instructor was teaching this. My textbook wasn't that clear either. Now, I understand it. Thanks for posting this video about how to do it.
Man! this is awesome. We get 4x4 or higher order in exams and it would take forever. Thanks for your help.
Thanks for making this video! Simple to remember!
You are a hero bro
I watched your video and it was self explanatory.I tried to watch another video to compare but I think you gave explanation to why the elements in the L matrix were so.Thank you sir.
Thanks so much! Best video I was able to find on LU factorization
THANK YOU! I appreciate it! This saved me right before my exam =)
Thanks a lot! I've been struggling on this for a long time.
Beautifully presented. Completely demystified what had previously been quite confusing. Thank you!
A great video explaining the shortcut method for LU decomposition.
Thank you so much. I think there is a need to make a revolution in university degree. TH-cam lessons are far more efficient than stupid useless 3 hour lectures.
you saved me with that explanation man! greetings from brazil!!
Saved me from soooooo much extra work thank you!
great was searching for a good explanation and example, and here i found it. tyvm
thank you a lot man, this is how you explain a method
Its 4 am now and i am watching this finally i learned thank you sir.
Writing my final paper for numerical methods tomorrow, this really helped a lot! Thanks :)!!!!!
Thanks Man 👍🙏. Thank You for making it this easy and Understanding.
Thank you for making this concept easy to understand. You are a Godsend for students like myself.
You are so welcome!
dude this clip is AWSEOM!!!!! now Ive got idea of this topic.
thx for this amazing vid
greetings from Seoul
Thank you so much! its the best video in all youtube for this topic! you made it super easy to understand!
I wonder how the hell does my lecturer spends 2 hours on this and noone still gets it, while this dude does it in 5 minutes
The best way is to visit the mathispower4u website. It has all of the videos in order by course and topic.
thanks a lot i wasn't able to understand LU decomposition from Meyer book but U solve this problem for me!
Makes much more sense now. thanks for the video !!
You made me understand it, superb person.
Thank you so much you dnt understand how easy you made this to understand
I clocked out in class for some dumb reason. Thank you for your help.
THIS IS COOOL WELL DONE!! Now it's easy to understand! Thank you!
Exam in 1 hour. You saved my life!
Thank you for the simple explanation, helped me wonders!
Very helpful. Thank you again James.
Im wondering about this too... And are we only allowed to multiply one of the row only? Like is 2R1+3R2 allowed? if it is, which number should we plug onto the L? -2? -3? -2/3? -3/2? will all give the same answer?
I have an exam in 15 hours, you just saved my ass XD
Great! I added it to a playlist to watch later if i ever need
Are there some matrices wherein this is not applicable? It doesn't seem to be applicable on this matrix im working on
Finally understood 😭🙌. Thank you!
You teached me this method better then my teacher.Thank you a lot.
Thank you SO much for this video. I understand it much better now. I really appreciate it :)
Really good explanation!! Thank you!
damn, this made LU's so much easier. cheers!
the quote at the end just changed my life...
thank you sir today is my papr and i got useful tricks...thanks alot
Thank you tomorrow i have exam this video is very good to explain LU
Incredible, looks so easy now... Thank you !!!
Best explanations EVER!
thank you so much, this video help me alot clearing out confusion.
Just one question. Say, in the first step, R22 becomes 0. What will you do in the third step then? Would you say that LU decomposition doesn't exist?
Very simple and concise !
Thank you very much.
Thank you brother.Great solution.
Nice work you did there!
Amazing video . Thank you for sharing your knowledge
Great work sir, it worth working
very helpful, simple explanation, thanks alot
Thank you for this very beautiful way of explanation s......
So easy to do these now :o
Thanks so much
Thanks....you made it easy for me...
great video dude, you help me alot
That’s what I need! Thank you for your help
Clear and lucid, thanks.
May I ask, what software and peripherals (mouse, stylus+pad, ... ??), and the OS you used to make your presentation?
Thanks, man! It was really helpful.
Thank you both for your help in understanding the idea and for your providing of this practical method of implementation! Much more clear than university material...
I just have one question...why does A need to be able to be reduced to U without row interchanges? Since this is also a row operation, that's not clear to me. Does this mean that, in practice, I cannot use techniques like Gauss pivoting to obtain U?
Sorry but I am pretty much a beginner in this field...
you are a god, thank you so much for this video
This is really awesome.
Thank you so much!
Thanks a lot for making it so explained and easy to understand... Btw, recommended speed is 1.4x :).
Thank you
Wish you all the best
You are incredible. Thanks a lot.
