4. (Applying LU and LUP decompositions) In this problem, we'll
use the LU/LUP decomposition to solve a linear system of
equations.
a) For A = [12 -8 13 -1 13;14 11 -5 -5 -7;1 -8 -9 10 8;-11 10 -8
3 8;-11 -8 4 2 -4] find matrices P, L, and U so that PA = LU using
Matlab's lu function. Based on your results: did Matlab use
pivoting during the lu-computation?
b) For b = [4;-4;-5;3;7] solve Ax =...
