1. (25 point) Write MATLAB codes using colon operators to create the following matrix A; Using a built-in function rand to generate a random 3 x 2 matrix B, in which each element is between 0 and 5. And then write commands to multiply matrix A by B and assign to matrix C. Then sort rows of C based on the second column in a descending order and assign the sorted matrix to D. Finally, retrieve all the elements in the second column of the resultant matrix D, and assign the elements to E. [2 1.1 0.2] A = 12 L4 7 10. 1.
