This is better than watching Netflix!! Amazing walkthrough

[@ozzyfromspace]

Nice! I forgot I was "learning" and just had fun with it! Brings back memories from my college days ☺️

[@TheBlenderer]

This is great, I like how you first do it manually and then write the program. Thanks!

great video...this helped me alot for my finals...

[@rajaamjadsajjjad3450]

I listen the video video is very helpful for me to solving assignment questions

[@TomCi00738]

Hi, how can i add the row swap to this code, could you help me please?

[@CarlosMontalvo251]

+pikadonte Row swapping is tough. You would need to add in something that checks to see if a zero pops up when it's not supposed to. Then if it does you would need to add a line of code that says temp = augA(row_original,:); augA(row_original,:) = augA(swap_row,:); augA(swap_row,:) = temp; The actual reason for row swapping is slipping my mind at the moment but I'll add row swapping to my to do list and try and post a video asap.

That video would help me a lot! Thanks for the reply.

Sorry this took so long. Here is a video showing you how to row swap. kzbin.info/www/bejne/eHTJm6RubZ1les0

Dear Sir please tell me if a matrix has 4*4 than what code use for it

[@CarlosMontalvo251]

This will probably work for any size matrix. I haven't tested it on anything larger than 4x4

[@rajaamjadsajjjad3450]

@@CarlosMontalvo251 Bundle of thanks Sir....... God bless you always........

Hi, I have an assignment about gaussian elemination and I didn't know how to solve it, can you help me with it please?

[@CarlosMontalvo251]

+mariam altenaiji I can try. What is the problem?

[@Mariamaltenaiji]

I have to write a general code for gaussian elimination, with considering the following -Display the augmented matrix. -Display the pivot P and the |Cpj| which is the maximum at which p is picked. The program should check whether there is a solution. -Display the augmented matrix after switching the rows, along with the indices of the switched rows. -Display the needed adjustment to produce zeros in the lower rows. -Show the matrix D and e. -Solve for the unknowns and show the results.

[@CarlosMontalvo251]

+mariam altenaiji Wow that's alot. But everything you are trying to do is in the code above. I'm not sure I could help anymore unless I did the assignment for you.

[@Mariamaltenaiji]

I won't say no, that'll be awesome hahaha

[@CarlosMontalvo251]

+mariam altenaiji Unfortunately I ethically cannot do your homework for you.
