MATLAB - 识别每个排版的符号(MATLAB - identification of every typesetted symbol)

 我在MATLAB中有以下代码，用户必须逐个字母地输入单词"precipitations" 。 键入一个字母后，用户必须按Enter键 ，程序将检查键入的字母是否正确。 
 
 现在我想更改程序，以便用户在键入字母后不必按Enter键 。 MATLAB中是否有任何操作符或函数对每个按下的按钮作出反应，因此不必按Enter键 ？ 
 
disp('Please enter "precipitations" without errors')
target=('precipitations');
n=size(target); n=n(2); % Characters number

for i=1:n;
    YourInput(i)=input('','s');
    if YourInput(i)==target(i)
        disp('OK. Please, input the next symbol')
        i=i+1;
    else
        disp('Error. Please try again.')
        break
    end
end

I have the following code in MATLAB, where the user has to enter the word "precipitations" letter by letter. After typing one letter, the user has to press Enter and the program checks, whether the typed letter was correct.
 
Now I would like to change the program, such that the user does not have to press Enter after typing a letter. Is there any operator or function in MATLAB which reacts to every pushed button, so one does not have to press Enter?
 
disp('Please enter "precipitations" without errors')
target=('precipitations');
n=size(target); n=n(2); % Characters number

for i=1:n;
    YourInput(i)=input('','s');
    if YourInput(i)==target(i)
        disp('OK. Please, input the next symbol')
        i=i+1;
    else
        disp('Error. Please try again.')
        break
    end
end
