Solve a System of Linear Equations Using LU Decomposition

[@mr.denver0075]

My guy, 12 years later and you're still a legend. I have my Numerical Methods exam tomorrow and was scared of this, but now I feel a lot more comfortable with this work. Much appreciated.

[@Mathispower4u]

Glad I could help!

YOU ARE ABSOLUTELY AMAZING! I've searched so many videos trying to understand how to do this and in two 8-minute videos, you explained it so clearly and simply. Thank you so much!

+Daniel Jr. I'm glad I was able to help out. Thank you for posting your comment.

Same here! Everything is cristal clear now. Thanks!

You're the absolute best man. When I was going through undergrad math in college, my institution implemented your videos into every homework assignment we had all the way from algebra to calc 3 and beyond. Thank you for what you do.

Thank you so much, a 3 hour lecture left me nothing but confused and you just explained it in under 20 minutes!

It's not even under 9 minutes

[@water5795]

4:00 why do we use row 2 and not use row 1, -r1 + r3 is still 0 but it’ll give different answer for l

[@Mathispower4u]

Good question. By using R2, we don't lose the 0 in column 1 in R3. If we use R1, we would lose the 0 in column 1 R3. You can technically use any two rows, but we don't want to lose 0's in the process. Whichever rows we use, it should not affect the answer as long as the row operations are performed correctly.

what if at 4:26 you did 3R3+r2. same way to make it 0 ,but would it then be -3 in ur L matrix?

@@Mathispower4u Yes Yes. Sorry to bother you, but can you tell me briefly what should I do when a line has only zeros and therefore LU multiplication cannot be done? I searched a lot for something like this on the internet and couldn't find it :(
