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 = [7 7 7 7]; B= 6:9; C= 3; D = 2; E = 8; F=[C,D,E,D]; i.) [1 1 1 1] = ? ii.) [0 0 1 0] = ? iii.) [10.0000 10.5000 11.0000 11.5000] = ? iv.) [0 1 0 0] = ? v.) [3 7; 2 7 ; 8 7; 2 7;] = ?
