(b) (Use the 'rand or 'randi functions in Matlab for creating random numbers). scalar c. (In all of them the random numbers should be between -11 and 2). (c) Using colon notation, replace the 3rd column of matrix A by the elements of (d) Use the new A matrix from part 2.c. Combine matrix A and vector b and create Create a random 3x3 matrix A, a random 3x1 column vector b, and a random vector b a combination matrix B in which the first three rows are the same as matrix A and the forth row is composed of the elements of vector b. (e) Create another 4x3 matrix C with random numbers between 5 and 9 (f) Calculate matrix D which is element by element division of C divided by B. (g) Using period notation, raise each element of vector b to the power of c (the random scalar created in part 2.b) and store the results in new vector e. (h) Save all the variables in a .mat file called p2Result.mat. (6) Save matrices B and D, and vectors b and e in a.txt file called data.txt 6) Print everything and submit in class
