while true
xs = input('enter your guess (a list of three numbers)', 's');
xs = regexprep(xs, '^\[(.*)\]', '$1');
s = regexp(xs, '(\s|,)+', 'split');
if length(s) ~= 3
warning('Wrong number of entries, need 3');
continue;
end
x = str2double(s);
if any(isnan(x))
warning('Something was not a number!');
continue;
end
break;
end
