use while loop to validate user input. the input must be a 1x3 row vectow, if not, the code must notify and promt the user to re-enter the vector in matlab

main.m
valid_input = false; % initialization of input validation flag
while ~valid_input % loop until input becomes valid
    user_input = input('Please enter a 1x3 row vector: '); % prompt for user input
    if isvector(user_input) && numel(user_input) == 3 % check for vector condition
        valid_input = true; % set input validation flag to true
        disp('Valid input received'); % notify user of valid input
    else
        disp('Invalid input, please try again.'); % notify user of invalid input
    end
end

In the above code, we first set the input validation flag to false, and we keep looping until the flag becomes true. Within the loop, we prompt the user to input a vector using the input function. We then check if the input is a 1x3 row vector using the isvector and numel functions. If the condition is satisfied, we set the validation flag to true and notify the user that valid input was received. Otherwise, we notify the user of invalid input and the loop repeats until valid input is received.
