User inputed vector - Index exceeds matrix dimensions.

I can't seem to get this code to have the user input the vector.

error message: Index exceeds matrix dimensions.

code below:

e = zeros(1,5);
cnt = 0;
while 1==1
    cnt = cnt+1;
    if (cnt == 6)
        break;
    e(cnt) = input('Elements:  ')
    end
end
e = e(1:cnt);
w=[16 12 14 32 1];
disp('molecular weight: ')
w*e

Because when cnt==6; you can't calculate e = e(1:cnt); (numel(e)=5)

Try doing it this way:

userString = char(inputdlg('Enter the numbers'))
theNumbers = sscanf(userString, '%f')

e = zeros(1,5);
for cnt = 1:5
  e(cnt) = input('Elements:  ')
end
