/* The decomposition PA = LU can be rewritten as A = P^{-1} L U.
* So we proceed as follows:
* Step 1: compute c = Pb.
- * Step 2: replace c by the solution x to Lx = c. Exists because L is invertible.
- * Step 3: replace c by the solution x to Ux = c. Check if a solution really exists.
+ * Step 2: replace c by the solution x to Lx = c.
