please help solve the equation
1 5 4 | x1 = 12
2 0 3 | x2 = 9
5 8 2 | x3 = 5
by using an LUP decomposition.
I really want to see step by step solution to get L, U and P.
Sorry I will finish the problem
replace with our factoriztion
Lets define this matrix equation
subbing into the above equation we get
solving this by a forward sub we get
Now subbing back into the equation for y we get
Now solving this by back sub we get
Sorry I didn't do this the first time
