clear
clc
n=10;
ii=1;
V=0;
display('number between 10 and 20!')
while ii<10
    teste = input('Enter a value: ','s')
    if strcmp(teste,'End')
        display('You cannot type end before you have 10 values entered')
        continue;
    end
    X(ii) = teste
    V(ii) = str2num(X(ii))
    ii = ii+1;
end
while (ii>10) | (ii<20)
    teste = input('Enter a value: ','s')
    if strcmp(teste,'End')
        display('End Program')
        break;
    end
    X(ii) = teste
    V(ii) = str2num(X(ii))
    ii = ii+1;
end

在 MATLAB Online 中打开

%for 10 values, while ii<11 is needed whe we start with ii=1, and
%string(teste) to convert character array into string
clear,clc
n=10;
ii=1;
V=0;
display('number between 10 and 20!')
while ii<11
    teste = input('Enter a value: ','s')
    if strcmpi(teste,'End')
        display('You cannot type end before you have 10 values entered')
        continue;
    end
    X(ii) = string(teste)
    V(ii) = str2num(X(ii))
    ii = ii+1;
end
fprintf('\n loop 2:');
while (ii>10) | (ii<20)
    teste = input('Enter a value: ','s')
    if strcmpi(teste,'End')
        display('End Program')
        break;
    end
    X(ii) = teste
    V(ii) = str2num(X(ii))
    ii = ii+1;
end
