🟢04 - Cholesky Decomposition Method (Algorithm)

In this lesson we are going to
Solve a system of linear equations using Cholesky Decomposition Method.
Steps Involved
1. We first represent the system in the form Ax = b,
Ax = b, decompose A = HH^T, H = lower Triangular Matrix with positive diagonal entries and H^T = transpose of H
HH^Tx = b, let H^Tx = y......(2), therefore,
Hy = b.....(1)

heya, mech engineering student from chile here, loved ur video, you explained it all so neatly and clean, thanks!

[@SkanCityAcademy_SirJohn]

Aww great , hope my English was cool

[@jozhou916]

So well explained :) and neat handwriting too! thanks for the video

[@SkanCityAcademy_SirJohn]

Awww you are most welcomr

Fellow Nigerian i say thank you

Most welcome, im rather a Ghanaian. Can you text me your contact?

[@Abineshvarun123]

Sir what will be the procedure if the matrix is not positive definite?

[@reemlol7715]

appreciate you!

Thanks so much

ciao complimenti per i video , anche non capendo l inglese riesco a capire i contenuti perchè spiegati veramente bene, riguardo all analisi numerica, avete fatto il video sul metodo delle potenze e sul metodo del gradiente?

professor in 17:32 h33 how did you come to the conclusion that it supposed to be square root of a33 - h31^2-h32^2. is it not supposed to have only one squared element? the formula is hkk = square root of akk - hkj^2 could you explain it briefly? id love to hear from you

[@SkanCityAcademy_SirJohn]

From the algorithm that has been given, h33 is what you see in the video, it's the right thing. H33 = sqrt ( a33 - (h31)² - (h32)² ) What you have said is for h22, When you want to find h44 = sqrt ( a44 - (h41)² - (h42)² - (h43)²)

What’s the j in the cholesky algorithm please?

для особо одаренных хотелось бы сказать что корень из числа всегда число положительное а не как у вас плюс минус... чушь
