The solution to a system A\vectx=\vectb of linear equations can be solved quickly if A can be factored as A=LU where L and U are of a particularly nice form.

In this section we show that Gaussian elimination can be used to find such factorizations.
The transpose of a matrix is an operator that flips a matrix over its diagonal. Transposing a matrix essentially switches the row and column indices of the matrix.
