Problem 4: Numerical programming: Gaussian elimination for multiple vectors of unknowns. Modify the code of Gaussian elimination with partial pivoting to solve for the solution of the following system of linear equations where X is a matrix, i.e., X has more than one column. Note that the idea is to solve the problem Ax b multiple times, where x is a one-column vector. Hence, the coefficient matrix A needs to be reduced to the upper triangular form only once. Apply your code to solve for the following system and check you answer with the result obtaine by applying the backslash operator (use format long and then x observation?) A\B; any unexpected 1-1 1 1 2 5 3 -1 -4 2 1 4 and B- 11 2 1 -26 Critical thinking: The system of equations can be viewed as A times the first column of X results in the first column of BA times the second column of X results in the second column of B, etc. In other words, use a for-loop to solve the solution of each column of X and then concatenate the solution vectors
