Using while statements to create a loop if a value entered is not correct

1 visualización (últimos 30 días)
So im writing a code right now which prompts the user to enter the a number from 1-3. ive created a while statement which creates a loop and prompts them to type the value in again untill its either 1 2 or 3. However when i run the code and type in 2 for example, which is a correct number, its staying in the loop as if ive entered a wrong number. The only number which gets me out of the loop is when i use the number one. I feel like my while statement is incorrect, Here is the code: (ignore the MaxT and MinT)
case 1
MaxT = 0; MinT = 0;
disp('You have chosen average time to complete')
prompt = ['Please type which cube you would like\n<strong>Option 1:' ...
'</strong>2x2\n<strong>Option 2:</strong>3x3\n<strong>Option 3:</strong>4x4'];
cube_choice_avg_time = input(prompt);
while cube_choice_avg_time ~= 1;2;3;
prompt = ['You need to enter a value of 1,2 or 3\nPlease type ' ...
'which cube you would like\n<strong>Option 1:</strong>2x2\n<strong>Option 2:' ...
'</strong>3x3\n<strong>Option 3:</strong>4x4'];
cube_choice_avg_time = input(prompt);
end
if cube_choice_avg_time == 1
Full_cube_data = xlsread("Full_Cube_data.xlsx");
specific_data = Full_cube_data(73:108);
Avg = mean(specific_data);
disp(['Average Time (s) = ', num2str(Avg)])
elseif cube_choice_avg_time == 2
Full_cube_data = xlsread("Full_Cube_data.xlsx");
specific_data = Full_cube_data(37:72);
Avg = mean(specific_data);
disp(['Average Time (s) = ', num2str(Avg)])
elseif cube_choice_avg_time == 3
Full_cube_data = xlsread("Full_Cube_data.xlsx");
specific_data = Full_cube_data(1:36);
Avg = mean(specific_data);
disp(['Average Time (s) = ', num2str(Avg)])
end

while ~ismember(cube_choice_avg_time, 1:3)

Write [1 2 3] instead of 1;2;3
