idea of GMRES as Krylov subspace method

[@sijiazhou6782]

Thank you for your explanation. It is clear and logical

[@suryanshvarshney111]

man, why did the video ended abruptly? what about the rest?

[@chainehistoire7616]

Thank you, the method is much more clear now Is it normal that the video ends before the explanation is finished?

[@WhatTheGuiz]

Too bad the video stops before we get to know the method to calculate those y vectors. Very helpful video nonetheless

[@thesuperintendentoffugues1144]

What is h_kj ?

[@daniel_an]

It the orthogonal (scalar) projection of Av_j to the vector v_k for k=1,...,j. In other words, you are subtracting the part of Av_j that can be represented by the previous vectors v_1 through v_j, and thus obtaining a vector in a new direction outside the span of the previous vectors

when i know something , the video stop,

[@spellfox_]

Its very quiet

[@yanmengyang2637]

too bad over

[@walidkhier]

I am glad I am not one of his students

[@daniel_an]

This was a graduate course, and it relies on knowing: Krylov method (which I have a different video on) and also Gram-Schmidt procedure of getting orthonormal basis from a basis. Sorry if it didn't make sense to you.

@@daniel_an The last I read about krylov subspace methods was around 1997. I still have some traces in mind. But frankly I was totally lost in the video. However, I agree with you in one point: I shouldn't judge a movie by seeing the last quarter. And in any case thanks for sharing your knowledge with the rest of the world.
