Question: 2. (a) Create MATLAB fu nction/which performs LU decomposition with partial pivoting. The function should-has the form (x) = LUSolver(A,b), where x is the solution

2. (a) Create MATLAB fu nction/which performs LU decomposition with partial pivoting. The function should-has the form (x) = LUSolver(A,b), where x is the solution of Ax- b. A is a n-by-n square matrix. (b) Test your program using the system 0x1 + 0x2 + 1x3-1x4 = Ozi + 1x2-4x3 + 1T4 = -18 lzi - 4x2 + 1x3 + 0x4 = 12 -1x1 + 1x2 + 0x3 + 0x4 = 3 Check your answers by substituting them into the original equations
