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) A = [777 7]; B= 6:9; C= 3; D = 2; E = 8; F=[C,D,E,D]; i.) [111 1] = ? ii.) [0 0 1 0] = ? iii.) (10.0000 10.5000 11.0000 11.5000) = ? iv.) (0 1 0 0) = ? v.) [37; 27; 87; 2 7;] = ? 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). 4 A -1 -3 16 -2 25 -7 9 0
