end
end
here is my code and when i type some example NRIC numb like S2307605 SO the odd numb suppose to be 39 BUT it doesnt and i still havent known wheres the wrong line

Lets fix your code too:

nric = 'S2307605';
assert(ischar(nric)&&numel(nric)==8,'The NRIC must have 8 characters.')
% Check if the first character is 'S' or 'G'
assert(any(strncmp(nric,{'S','G'},1)),'The first character must be "S" or "G".')
% Check if there are any non-digit characters in the numeric portion of the NRIC
numericPortion = nric(2:end);
assert(all(isstrprop(numericPortion, 'digit')),'The numeric portion of the NRIC should only contain digits.')
% Extract the first character to determine the status
status = nric(1);
% Convert the numeric portion to a numeric array
numericArray = sscanf(numericPortion,'%1d',[1,Inf]);
% Calculate the sum of digits in odd-numbered positions
oddSum = sum(3*numericArray(1:2:end));
% Sum the digits in even positions
evenSum = sum(numericArray(2:2:end));
% Calculate the total sum
totalSum = oddSum + evenSum;
% Calculate the remainder when divided by 11
remainder = mod(totalSum, 11);
% Display the intermediate calculations
fprintf('Odd Sum: %d\n', oddSum);
Odd Sum: 39
fprintf('Even Sum: %d\n', evenSum);
Even Sum: 10
fprintf('Total Sum: %d\n', totalSum);
Total Sum: 49
fprintf('Remainder: %d\n', remainder);
Remainder: 5
% Determine the checksum letter based on the status
if status == 'S'
    checksumLetter = getChecksumLetterS(remainder);
elseif status == 'G'
    checksumLetter = getChecksumLetterG(remainder);
else
    error('Invalid NRIC format.');
end
% Add the checksum letter to the NRIC
nricWithChecksum = [nric, checksumLetter];
fprintf('NRIC with checksum: %s\n', nricWithChecksum);
NRIC with checksum: S2307605F
function letter = getChecksumLetterS(remainder)
switch remainder
    case 0
        letter = 'A';
    case 1
        letter = 'B';
    case 2
        letter = 'C';
    case 3
        letter = 'D';
    case 4
        letter = 'E';
    case 5
        letter = 'F';
    case 6
        letter = 'G';
    case 7
        letter = 'H';
    case 8
        letter = 'I';
    case 9
        letter = 'J';
    case 10
        letter = 'K';
    otherwise
        error('Invalid remainder.');
end
end
function letter = getChecksumLetterG(remainder)
switch remainder
    case 0
        letter = 'K';
    case 1
        letter = 'L';
    case 2
        letter = 'M';
    case 3
        letter = 'N';
    case 4
        letter = 'O';
    case 5
        letter = 'P';
    case 6
        letter = 'Q';
    case 7
        letter = 'R';
    case 8
        letter = 'S';
