upper case need help
显示 更早的评论
function unscramble=latinCipher(scramble)
[str,shift]=strtok(scramble,' ');
shift=str2num(shift);
str=char(mod(double(str)-97+shift,26)+97);
unscramble=upper(str);
end
for my this code, if I put lowercase 'sknz 4' it will output as 'WORD'. How could be fixed by puting uppercase 'SKNZ 4' would output as 'WORD". Because for now if I input 'SKNZ 4' it showed an unexpected value.

Your input might be either upper case or lower case, and you want the two to be treated the same way, and the rest of your code assumes it was lower case. That makes the easiest approach to just use lower() to convert uppercase to lowercase (leaving lowercase alone.)
