Write two user-defined MatLab functions that implement the LU decomposition method using Doolittle's decomposition. The one function LUdecom should transform the coefficient matrix [A] to the Doolittle's decomposed form [L/U] and the second LUsolut should solve the set of equations. Apply the algorithm with the system of equations in question 1 and report the results.
