Gaussian Elimination and Gauss Jordan Elimination (Gauss Elimination Method)

[@Crazytime101PlayzGames]

Imagine struggling so much with something and spending hours trying to comprehend its existence just to find this dudes video and finish them in 20-30min with a complete understanding of what you did. Thank you sir.

[@majinDuu]

For the entire semester I couldn't understand this and you taught me it in 15 mins. Damn. I feel blessed to have come across this video

[@BriTheMathGuy]

Very glad I could help! Have a wonderful day.

[@yesufhassen7422]

@@BriTheMathGuy I was struggling the whole week, and thank you very much for your clear explanation it's absolutely clear now. What about if I leave 2 as a coefficient at 5:39 and eliminate 3 to make 0 the underneath? Should the coefficient always be 1?

KZbin needs to introduce the "Love" reactions just like Facebook because this video deserves way more than just a like

[@BriTheMathGuy]

Wow! Thank you very much. :)

[@98tutorialguy]

Thanks for pointing out the difference between them, the names initially confused me so I thought they were the same thing.

[@BriTheMathGuy]

You're welcome!

[@jackoneill348]

Well, I came to this video to find the difference between these two algorithms and I must say I did *not* obtain the answer. What is presented in the video are not two different algorithms, but two viewpoints on the same algorithm. You are doing literally the same computations. I think (although I am not sure, I am still looking for some reliable reference) that the point is that you are *never* supposed to normalized the rows. Then it actually becomes different, because in case of Gauss you do the divisions during the back substitution, while with Gauss-Jordan, you do them at the very end. Due to this difference, Gauss uses less operations, while Gauss-Jordan is maybe more numerically stable.

[@dani-ou4uu]

after watching countless videos, this was the one that finally made me understand. thank you!

[@jwoodsonmusic]

Thank you so much! I watched my teacher's one hour lecture on the three times, and it didn't even get me to a quarter of the understanding this video did! You're literally a lifesaver.

[@BriTheMathGuy]

You're very welcome!

[@LordMonteq]

here in 2021...when trying to make the 2 in the y column a 1, you can also subtract R3-R2 and this should save you time and not give you any fractions.

[@aarontyler6599]

i have watched so many vids on this. this is the single most succinct video EVER. thanks

I have an exam tomorrow and I did not understand this entire unit when I was "taught" by my professor, I thought I was just dumb but I guess I just have a bad professor who can't take the time to actually teach his students the material. You taught me more in this 15 minute video than my professor ever taught in a 65 minute lecture. thanks, I think I will be ok after all.

Linear Algebra exam tomorrow... this is gonna be a big portion of it. This cleared a lot up. Both methods yield the same result, however more computations need to be made for GJ, and as a CS major, we take this into account in my course so that is the downside but GJ makes a lot more sense to me. I was confused but you cleared it up big time. Thank you!

[@TheAquaticBeef]

Man, that's pretty cool! Maths is actually pretty cool! This is mind blowingly awesome to me. Why does this work?

[@BriTheMathGuy]

I know right! This basically works because of basic algebraic operations work on equations, and the fact that adding(subtracting) equations is a valid thing to do. The main difference here is we are just doing a shorthand notation by using a matrix. Have a great day!

[@iWinsomeLosesome]

[@BriTheMathGuy]

Thank you for the video, it was incredibly helpful. For Gaussian Elimination, do you always need to have leading 1's in the diagonal? My instructor said that the numbers along the diagonal do not matter as long as whats underneath them are 0's. Is that true? Or is it better to stick with using 1's along the diagonal?

[@graespargo3605]

this was really helpful. thanks

[@BriTheMathGuy]

You’re welcome. Have a great day!

[@kaushikmysore6608]

In the Gauss-Jordan method, should the 1's always be from the top left corner to the bottom right corner or does it not matter?

[@BriTheMathGuy]

You could do it from top right to bottom left, but the method in this video is the standard (and probably most natural) way to do it. Thanks for watching!
