🟢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!

[jozhou]

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

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

[ciccio]

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?

What’s the j in the cholesky algorithm please?

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

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