I am having problems setting this up "In the main script file, prompt the user for ? through appropriate use of an input command (doc input) and while loop (doc while) to ensure that ? is an integer value (doc rem) and greater than or equal to 1. Also, prompt the user for ? through appropriate use of an input command and while loop to ensure that ? is a real value (doc isreal) and is greater than or equal to 0.5." This is what I have but it isn't working correctly.

clear

clc

n = input(['Enter value for n >> ']);

while ((n >= 1) && (rem(n,1)~=0))

disp(['The answer must be an integer and greater than or equal to 1'])

n = input('Enter value for n >> ');

end

x = input(['Enter value for x >> ']);

while ((isreal(x)) && (x >= 0.5))

disp(['The answer must be real and greater than or equal to 0.5'])

x = input(['Enter value for x >> ']);

end

在 MATLAB Online 中打开

n = input('Enter value for n >> ');
while ~((n >= 1) && (rem(n,1)~=0))
    disp('The answer must be an integer and greater than or equal to 1')
    n = input('Enter value for n >> ');
end
x = input('Enter value for x >> ');
while ~((isreal(x)) && (x >= 0.5))
    disp('The answer must be real and greater than or equal to 0.5')
    x = input('Enter value for x >> ');
    
end
