LU factorization
Ax=b where A=LU
LUx=b
L(Ux)=b Ux=y
L(y)=b solve for y then use y to solve for x

Question

LU factorization 
Ax=b  where A=LU
LUx=b  
L(Ux)=b            Ux=y
L(y)=b  solve for y then use y to solve for x

Is this a good simplification of the LU factorization

anonymous · Answer

where L is the lower triangle matrix and U is the upper.

yeah, this has something to do with row eschelon form

anonymous · Answer

Do you know why we would use this method instead of simply solving for x using A?

amistre64 · Answer

i recall reading about it in my textbook

amistre64 · Answer

decompositions are helpful in some instances but I cant recall specifics

anonymous · Answer

I know it's used in electrical engineering but our prof doesn't want us to do that part ...guess just showing us another method to solve for x
