Put workspace data into menu and prompt someone to select it

6 views (last 30 days)
Homework Question:
Prompt the user to select a day and a location based on the data provided. On the command window, output the day, location, and ice thickness [m] for that day. NOTE (avoid hardcoding): Your code should produce different results if the data for Ice changes. The options for the location or day chosen should change if the number of values in LocationID or Days changes.
load('MA2_data_2.mat');
days1= string(Days);
select_day1 = menu('Please select a day',days1(:));
ice1 = string(Ice);
select_loactionID = menu('Please select location',LocationID(:));
How do i get it to load ice based on the day and location chosen

Capture their button number into a variable then use it somehow
load ('MA2_data.mat');
dayButton = menu('Please select a day',string(Days));
locationButton = menu('Please select a location',LocationID);
chosenDay = Days{dayButton};
chosenLocation = LocationID{locationButton};
Ice = 0; % whatever you do to get its value..................
fprintf('On Day %s, at location %s, the ice thickness was %0.4f [m]', chosenDay, chosenLocation,Ice)

Sorry - it was untested because I had not taken the time to download the mat file, but since you seem to have found a problem, I did. But I'm sure you're a smart enough engineer to have already made the corrections, but here they are anyway:
s = load ('MA2_data.mat')
Days = s.Days
Ice = s.Ice
LocationID = s.LocationID
dayButton = menu('Please select a day', string(Days));
locationButton = menu('Please select a location', LocationID);
chosenDay = Days(dayButton)
chosenLocation = LocationID{locationButton}
chosenIce = Ice(dayButton, locationButton)
fprintf('On Day %d, at Location %s, the ice thickness was %0.4f meters.\n', chosenDay, chosenLocation, chosenIce)

No problem, but make sure you read that link about cell arrays. It will give you a good intuitive idea of how to work with them. Also, can you Accept the answer if we're done here? Thanks in advance.
