Question

10. (12 points) The arrays price A, price B and price C given below contain the price in dollars of the three stocks over 10 days. price A = [19, 18, 22, 21, 25, 19, 17, 21, 27, 29] price B = [22, 17, 23, 24, 18, 16, 25, 28, 27, 27] price C = [10, 11, 12, 13, 19, 17, 20, 21, 24, 28] For the stock data, write a MATLAB code to plot the stock price vs. days graph for all three stocks on the same figure. Also, add the xlabel, ylabel, title and legend. (copy the plot figures and paste here too)

Answer 1

Code:

a1=[0 19 18 22 21 25 19 17 21 27 29] %Array for price A

a2=[0 22 17 23 24 18 16 25 28 27 27] %Array for price B

a3=[0 10 11 12 13 19 17 20 21 24 28] %Array for price C

x=[0 1 2 3 4 5 6 7 8 9 10] %No. of days for x axis

plot(x,a1,x,a2,x,a3) %Plot the graph

xlabel('Days') %Label for x-axis

ylabel('Stock Price') %Label for y-axis

legend('Price A','Price B','Price C','Location','southeast') %Legend of the graph

Output:

30 25 20 Stock Price 15 10 5 Price A Price B Price 2 4 6 8 10 Days
