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;

%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

Okay, now it worked. I just had to reverse the order of the vectors X (ii) and V (ii).
X (ii) = str2double (test)
V (ii) = X (ii)
I didn't remember the strcmpi function, thanks.
