3 Plotting

Open and edit the script q3.m provided to you to answer the parts of this question.

(a) [1 mark]

Make a column vector named yr having the values 2009 through 2018 in steps of 1. Your vector should have 10 elements.

(b) [1 mark]

Make a column vector named co2 having the following values (you can copy-and-paste the values):

386.9, 388.7, 391.3, 393.1, 395.5, 397.9, 400.0, 402.5, 406.1, 408.0

These values represent the atmospheric concentration of carbon dioxide in parts per million for January of each year from 2009 to 2018.

(c) [4 marks]

To the script add the MATLAB commands needed to plot the values in the vectors yr and co2 to reproduce the following figure:

Running the script should reproduce the above figure exactly (including the limits of the axes).
