Question

Problem 3 (13 pts): (modified from Attaway Problem 3.39) a) (5 pts) Using the Matlab rand () function, create a script that generates a row vector (1 row X 20 columns) of random numbers, each with magnitude between 0 and 5 b) (3 pts) Use the round() function to turn all of the values into whole numbers by rounding down (truncate the decimal part on your vector) c) (5 pts) Add code to your script to generate a new vector of the same length (1 row X 20 columns) that tells you whether or not each value of your vector is even (a value of for "true") or not (a value of 0 for "false"). For example, if Vector [1, 3, 4, 2, 1, ....] Hint, your code should use a for loop to move through each of the 20 indices ofyour vector You will also need to use an if statement within that for loop to decide whether or not a particular value is even or not. You can figure out ifa value is even or not by using the mod0 function, which essentially returns the remainderfrom dividing using long division. For example, mod(Vector(3), 2) will give the remainder from division of Vector(3) by two. I.e., ifany whole number, x, is odd, mod(x,2) -I. Ifany whole number, x, is even, mod(x,2) 0 Another note: in our class discussion of the if statement, we covered the inequalities >, <, >, but did not discuss exactly equal to and not equal to. You will need to use "exactly equal to"for this homework. Syntaxt for all are shown below yntax less than ter than less than or equal to than or equal to exactly equal to

Question a) a#0; b = 5; % By default, rand returns normalized values (between 0 and 1) % To change the range of the distribution to a new range, (a, b), % multiply each value by the width of the new range, (b- a) and then 3hift every value by a vector -a(b-a) rand (1,20) Question b) vector-round (vector); Rounding the values Question C) PartCAns zero3 (1, length (vector)); for k= 1 : numel (vector) % Initializing vector of same length if mod (vector (k), 2) 0 if number 13 even % corresponding element in PartCAns is 1 % else (case odd) % corresponding element in PartCAns 13 0 else PartCAns(k) =0; end end % Printing results fprintf("\n vector =\n"); disp (vector) fprintf("\n PartCAns =\n"); disp (PartCAns)

% Question a)
a =0;
b = 5;
% By default, rand returns normalized values (between 0 and 1)
% To change the range of the distribution to a new range, (a, b),
% multiply each value by the width of the new range, (b – a) and
% then shift every value by a.
vector = a + (b-a)*rand(1,20);

% Question b)
vector = round(vector);         % Rounding the values

% Question C)
PartCAns = zeros(1,length(vector));   % Initializing vector of same length
for k = 1 : numel(vector)
    if mod(vector(k),2) == 0        % if number is even
        PartCAns(k) = 1;            % corresponding element in PartCAns is 1
    else                            % else (case odd)
        PartCAns(k) = 0;            % corresponding element in PartCAns is 0
    end
end
% Printing results
fprintf("\n Vector =\n");
disp(vector)
fprintf("\n PartCAns =\n");
disp(PartCAns)
