1. Write a function with the header [m, U, x] = mySweep(A,b) which performs systematic linear transformation on the system Ax=b (the forward sweep). Note that this function should return not only the transformed A and b, but also a matrix m containing -m(i, j) used in the

transformation but also with 1s on its diagonal. Recall that m(i, j) = -A(i, j) / A(j, j)

Since m will only populate with elements below the diagonal, you should first initialize m with nxn zeros.
