🟢03a - LU Decomposition : Example 1

In this lesson we are going to
Solve a system of linear equations using LU Decomposition.
Steps Involved
1. We first represent the system in the form Ax = b,
Ax = b, decompose A = LU, L = lower Triangular Matrix and U = Upper Triangular Matrix
LUx = b, let Ux = z......(2), therefore,
Lz = b.....(1)

Thanks so so much. Keep watching for more

[@11reinvented]

Definitely the most complete explanation of LU decomposition.

[@SkanCityAcademy_SirJohn]

Aww thanks so much

[@redefined4657]

Best LU decomp video online. You're helping with my semester exams. Thanks from India.

[@SkanCityAcademy_SirJohn]

Awww 🥰, that's a great feeling. Isn't it?

[@hk254lyt8]

You are saving my computer science degree . Respect from 🇰🇪 🫡

[@SkanCityAcademy_SirJohn]

Thanks so so much.

kuokoa sem mazee 😂

[@abdallahneymar8615]

Which means for u you don't have to make the principle diagonal 1s. We just change the entries under the leading entries to zero

[@HashemAljifri515]

Thank you so much man you are explaining in a very clear way!! I really appreciate people like you truly 🙏🏻. You got a new subscriber

[@SkanCityAcademy_SirJohn]

Awww thanks so much

I study actuarial science a.k.a insurance mathematics and I have an exam tomorrow on this subject.
Cheers from Indonesia

[@SkanCityAcademy_SirJohn]

Thanks so so much.... And God luck in your exams

[@ephraimsondoyi9966]

EEE here i have an exam tomorrow

[@SkanCityAcademy_SirJohn]

@ephraimsondoyi9966 best wishes

[@newtonsimiyu2705]

very great work to include explanation for LU calculation

[@SkanCityAcademy_SirJohn]

You are most welcome

[@abdallahneymar8615]

Sir please if you dont reply this question am dead😂 please is it that u aren't using the doo little and crout and cholesky but rather a different method or because i love this but you using row operation has made me a little bit confused. Which method is this please i realised most of them use alphabets

[@SkanCityAcademy_SirJohn]

Wow
The elementary row operation is quite simple oo. Can you go over the video again to see if it will be cool?

[@rexallassani2321]

this video makes me finally rest🤝🏼

[@SkanCityAcademy_SirJohn]

Aww that's a great feeling, isn't it? 😁
Where do you watch from?

I love you

[@SkanCityAcademy_SirJohn]

Aww thanks so so much
Please where do you watch from?

[@bahattineren1773]

Should we deploy partial pivoting?

[@SkanCityAcademy_SirJohn]

Under LU decomposition?

[@bahattineren1773]

@@SkanCityAcademy_SirJohn actually I wanted to say that diagonally domination.
