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)

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?

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

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

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)
