2. Consider the matrix A and Matrix B presented below. The operation to move from matrix A to matrix B is to update a tableau in the simplex tableau method. In this case, the first column is the pivot column and the third row is the pivot row. Matrix A= 4 8 0 1 0 0 150 2 -3 -1 0 1 0 50 2 0 0 0 80 Matrix B= 0 2.8 8 0 1 0 -0.6 102 2 -3 -1 0 1 0 50 1 0.4 0 0 0 0 0.2 16 a) Write a MATLAB code to obtain Matrix B from Matrix A. assume that you already have Matrix A in MATLAB with the name of A. The pivot element is equal to one other values equal to zero
