LU gives permutation vector, Lower and Upper decomposition.

Hi Salvo,

In LU() help, I see the screen capture attached. Is this missing in your version?

For square matrices, LU returns a list: {Lower Triangular, Upper Triangular, and Permutation}. Using the factors from the list, returns your original matrix.
