Positive semidefinite and positive definite matrices (visualize)

Visualization of Positive semidefinite and positive definite matrices. Verbal explanation, no writing used.

[@AmanDalmia]

Months of struggle in understanding and forgetting every time came to end. I guess I would never forget this concept. Thanks much.

[@iTzAdam5X]

thank you! Easy to understand and I love being able to have geometric interpretations for this stuff

[@sg5218]

Legendary. Thank you for blessing the world with this video.

[@shivaprasadbk2027]

By visualizing we get a better, intuitive idea of the concept. Superb explanation! Thank you!

[@whiteshadow3000]

Thank you very much for the explanation, it was very useful. One piece one constructive critique though, I think you repeated too many times the concept of "direction". But overall it was very useful, thank you!

[@giantneuralnetwork]

Really interesting visualization! I never thought of it that way but it’s right there in the definition. Thanks!

[@noteuler314]

If this concept is exactly like he has explained, then it's really amazing video 💯

[@matmektep]

Thank you a lot. This is much intuitive and better than long technical calculations.

[@cupckae1]

Summary: Hit vector v with matrix A we get the new vector v'. Now if angle between v and v' is

[@user-cc8kb]

Great intuition. Thank you very much!

Bro! im a grad student. Thank you so fucking much/!!!!! Dont need mit profs. Need you!!!!

[@bernardofitzpatrick5403]

Very clear explanation. You are a great teacher! thank you !

[@fugpug5646]

Thankyou soooo much brother. This really helped me out!!!

[@Vipinkalappurath1]

Great!! even a student without strong mathematical understanding can understand. I wish if you were my maths teacher!!

[@dpalmer4588]

fantastic description! thanks !

[@stacij1]

Good explanation man, helped me understand LQR Method in control theory a lot better.Cheers.

super

[@AnjuAnju-tx9qz]

Sir please upload more vedios

[@syaketyadav6310]

I guess this tutor has served as a submarine engineering in army😂😂

[@MLDawn]

Dot product between matrix A and the vector?! Not sure if I follow... so you mean A.x is a dor product with a result that is a scalar, let's call it S, and If S>0 then A is positive definite?! I thought we had to do xAx to get that scalar S!

[@prashanth5995]

That's right @5:08, sir says that x.Ax >= 0.

[@ankur-dhamija]

You are a fucking Legend...Prof Strang took 50 mins to explain this and you did it in 5 :-)

[@Yeahmansingh]

aye thanks

[@gateconceptinjust1minuteby317]

I love you prerana

[@samuelokoroafor4165]

you wasted too much time for too little information. try to work on that

[@itstoogooditswaytoogood3211]

is this a joke? this video teaches you the topic in 5 minutes for free. not only that but without writing a single thing on a piece of paper and in such a way that you don't even need to know any linear algebra to get the concept. dumb comment

[@fugpug5646]

@@itstoogooditswaytoogood3211 you’re completely right man. Can’t find this kind of explanation anywhere else
