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 = 1777 7); B= 6:9; C= 3; D = 2; E = 8; F=[C,D,E,D]; i.) (1 11 1] = ? ii.) [0 0 1 0) = ? iii.) (10.0000 10.5000 11.0000 11.5000) = ? iv.) [0 1 0 0) = ? v.) (37; 27;87; 27;] = ? b) Consider given matrix A below. Write a MATLAB program that computes the matrix B by computing square root of all the elements of A whose values is greater than or equal to 1, and adding 15 to other elements of matrix A. Compute the matrix B in a vectorized way (which means no loops). (10 points) 4 A= -1 0 -3 16 -2 25 -7 9
