Recursive Matlab function

Write a recursive Matlab function TriUVRCol that solves a virtually upper triangular system of equations accessing the matrix by column. Write another recursive Matlab function LUPivRec that recursively computes the LU decomposition of a matrix using partial pivoting. Then use these two programs on a third Matlab program GaussDriver to solve a square system of equations. Your functions should be as efficient as possible, taking into consideration all the computational points that have been given in class. Use your functions to solve Ax = b, with A and b given in the first question.
