Question 3. User input, using matrix indices to extract or add data, fprintf. You will design a short interactive program that allows the user to ask questions about one of four planets. A) Below you will see a table with information about four planets in our solar system. Enter only the numerical data into MATLAB in a 3x4 matrix called PlanetData or a similar variable of your choice. Earth Jupiter Mars Venus # of Moons 1 7.9 2 0 gravity in m/s Length of day in hours 9.8 23.1 3.7 8.9 24 9.9 24.7 2082 B) Create a menu which allows the user to select which planet they would like to know information about. C) Depending on which planet the user selects, use a MATLAB command to extract the data in that column and store it in a variable called Select Data or something similar. D) Use a fprintf statement to output onto the screen a sentence that says, "The planet you have chosen has X moon(s), a gravitational acceleration of X m/s and X hours in the day." where "X" is the actual number. E) You have just heard on the news that Pluto IS a planet!!! Celebrate by using a MATLAB command (or commands) to add a fifth column to PlanetData containing the following information about Pluto: moons 5, gravity 0.7m/s, and length of day-153.3 hours. This can be done in one line but it's okay if you do it in more.
