Wow, bravo sir. This is the only video that made elementary matrices make sense. I can't believe this doesn't have more views yet. The best explanation online period

[@robertbillette4671]

I'm from Michigan. I Studied abroad at HKUST a few years ago. Man I wish I had you as an instructor. You're so clear with your teaching style. Love the school though, great place

[@ProfJeffreyChasnov]

Thanks!

[@dark6.63E-34]

Simple and clear as it should be! Brilliant work

[@pluto5987]

thank you so much ! finally understood the significance of elementary matrices

[@michapeka2800]

Love it! Thanks for clarity!

[@xiaoxuanwang2570]

Very high quality teaching. Thank you!

[@shaikhfaizan3405]

Thankyou so much sir. You made it easy for us to understand this concept.

[@debbydambani7040]

best explanation ever...thank you dear sir...

[@imk820]

amazing lecture series. superb

[@MrDavidRaw]

real one, thank you

[@bite7326]

finally all these matrix multiplication rules have a point

[@lancelofjohn6995]

Nice lecture!

[@joshithmurthy6209]

thanks for the video

[@mohammadbayat1635]

Thanks man!

[@shadmanshakib5568]

Helpful ☺

Best ever

Correction, elementary matrix is an identity matrix with one entry changed. This means one of the diagonal ones could be changed to another number too. Not necessarily just the zeros.

Thank you

Hi Jeffrey, thank you for grate videos. Trying to folow every step but I have an issue with obtaining M3, could you possibly elaborate a bit more on how you obtain the 0 0 1 on the third row of the M3 by showing in more details of the rows used to multiply by the -1 factor and derive row 3 of M3. I also would like to ask you of any good matrices algebra books to cover the topics in great details for projects possibly containing thousands or few hundred thousands of equations, I see how you obtain the third row of M2 but not M3 as I get 3rd row of M2 again and not M3, thanks a lot.

Have a look at my lecture notes: Matrix Algebra for Engineers.

i shouldve clicked this video the first time it came out in the search results. i clicked on half a dozen other before i came across this perfect video! please forgive me 😣

[@al_7016]

Good... the marker color is pink but the written work is showing blue color.😎😀

[@adinandyala]

I thought you as Jeff Bezos from the thumbnail. Btw, thanks sir! This video was really helpful...

GIGACHAD I SHALL REMMEBER YOU WHEN I GET THE BARE MINIMUM GRADE TO PASS

[@just-code2093]

this left me very confused..

[@vallinayagamsenthil6569]

Such a good professor but why didn't you get reach

[@ProfJeffreyChasnov]

Not too bad overall. Trying to get students into my Coursera courses, which have a complete curriculum.

[@mkjav596]

we end up with MMMA

[@TheOriginalArchivist]

Why am I paying big bucks for lectures that are so much lower quality than free YT vids?

[@ProfJeffreyChasnov]

I take that as a compliment.

[@TheOriginalArchivist]

@@ProfJeffreyChasnov You should. You're a fantastic lecturer! Will definitely be watching more.

[@mouadaz9110]

if this man is real? look like BOT made by artificial intelligence? XD

[@ProfJeffreyChasnov]

Not nice

@@ProfJeffreyChasnov The net is full of trolls. I've just started a PHD after working for many years as an engineer. These lectures are fantastic.
