Question

Write a script in MATLAB that prompts the user to do a, b, & c.

a.)script that prompts the user to enter the day of the week using the input function. If the information the user enters is equal to “Saturday” or “Sunday”, display “have a nice weekend” in the Command Window. Otherwise, display “Good luck in your class lectures and your studies.”

b.)script that prompts the user to input the following array by providing an example in the prompt: [2 4;6 3;5 9]. Check if the user has input the array properly. If the information entered by the user is correct, display a statement to the Command Window informing the user they have entered the array correctly. If the user has not entered the array correctly, display a statement to the Command Window notifying the user that they have not entered the array correctly.

c.)script that prompts the user with the selection window provided on the next page (using the menu command) and then saves the user’s response as ‘user_val’. Then, print the string on the button associated with the user’s response in the command window.

Answer 1

% Matlab script that performs tasks a,b and c relating to input and menu

% a
% input of day of the week
dayOfWeek = input('Enter day of the week : ','s');
% use strcmpi to compare if input is sunday or saturday (strcmpi for case
% insensitive comparison)
% weekend
if (strcmpi(dayOfWeek,'Saturday') == 1 || strcmpi(dayOfWeek,'Sunday')== 1)
fprintf('Have a nice weekend\n');
else % weekday
fprintf('Good luck in your class lectures and your studies.\n');
end

%b
% input an array of size 3 rows and 2 columns
array = input('Enter a 3X2 array (eg - [2 4;6 3;5 9]) : ');
% check if user input array is correct and display the message accordingly
if(size(array,1) == 3 && size(array,2) == 2)
fprintf('You have entered the array correctly\n');
else
fprintf('You have not entered the array correctly\n');
end

%c
% Colors is the header of the menu and Red, Blue, Green and Yellow are the
% button values (replace the text as given in the selection window) (as
% screenshot is not provided using sample value)
% create a cell array of button choices for menu
menu_choices = {'Red','Blue','Green','Yellow'};
% display menu and get the index of the button seleced by user in user_val
user_val = menu('Colors',menu_choices);
% display the string on the button stored in index user_val
fprintf('You selected : %s\n',menu_choices{user_val});
%end of script

Output:
