Question

In Matlab

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

x = linspace(1,10,10);

a=[19,18,22,21,25,19,17,21,27,29];

b=[22,17,23,24,18,16,25,28,27,27];

c=[10,11,12,13,19,17,20,21,24,28];

plot(x,a);

hold on;

plot(x,b);

hold on;

plot(x,c);

xlabel('days') ;

ylabel('Doller($)') ;

legend('a','b','c');

title('Stock data');

Stock data 30 25 Doller($) 20 15 10 0 6 8 10 N days
