4. a) Using the following variables write a single line MATLAB codes to retrive given output. (You need to use at least two of the variables for each solution. Using scalar values is allowed along with the variables)(Hint: consider logicals for some of them).(20 points) A = [77 771; B= 6:9; C= 3; D = 2; E = 8; F=[C,D,E,D); ..) [111 1] = ? ii.)
