Using matlab solve the following

Consider the following arrays. A = [3 0 2 -6 2 5 -4 9 -5 -1 -4 1] B = 6 * A + cos(5 * A) - exp(A/3) Write MATLAB expressions for each of the following operations and SHOW their numerical results. Select the third column of B. Use element-by-element addition to find the row vector that is the sum of the second row of A and the third row of B. Find the maximum value in the vector resulting from element-by-element multiplication of the second row of A with the last row of B. Use element-by-element division to divide the first three elements of the second row of A by the fourth column of B. Find the sum of the elements of the resulting vector. Raise each element in the first column of B to a power equal to 1/4 th the corresponding value in A. Sort the rows of cos(A+B) in descending order
