Linear Algebra - Lecture 24 - Elementary Matrices and Inverses

In this video, we will discuss elementary matrices and their relationship to invertible matrices. We will prove a theorem that explains how to tell when a matrix is invertible, and how to find the inverse of an invertible matrix.

[Brahma]

It is a elegant explanation of elementary matrices. Thank you James

[SaiyanBranch]

In the beginning I think you meant adding -4 R1 to R3

[steveying]

This is the best explanation for the means of deriving the inverse matrix, thanks so much James!

[kerduslegend]

My guy!! You explain it better than my college professor.. All my profesor did was "here's your equation, don't ask how you get it, just use it" Like... Bruh💀

[piyush]

What a quincidence I m watching this video on 7 June 2020 ... Exact 2 years after this vdeo uploaded 🤣🤣😎🙂🙂

[VersatileAnthem]

sir, you are just awesome .the most clear explanation i got....thank you so much.may Allah give you blessings

[jun]

13:35 I wish you showed all the steps instead of talking over and only writing the final answers.
Otherwise, very helpful video thank you for your time .

[trollmasterpoop]

speedran thru the calculations like a mad lad.

[dhanamillionaire]

Thank u for explanation...this really helped me to understand ♥️👍

[wmd]

Thank you, considering an arbitrary matrix is the best way to describe elementary matrices! Wish I found this months ago.

[samuelromero]

Thank you my teacher did not explain this at all.

[aliosmanmusuloglu]

Thank you so much, James :) It is the best explanation i've ever seen.

[adinandyala]

Hey! I didn't understand the last part (15:00). Can anyone please break it down for me in simpler terms...

[michalhellman]

Incredibly appreciated. Very well done video.

[ryanjacksonx]

Is there a quick way of finding A=EU by hand?

[muhtasimrabib]

Don't you mean adding -4 . row 1 to row 2

[MrPowderhound]

Is it possible to find the inverse of an mxn matrix or do inverse matrices only exist on square matrices?

[ibile]

Why do I still pay in expensive university???
