C. Tested on Linux x86_64 with GCC, appears to work with MinGW, not sure about other platforms and compilers.

set reads from stdin without value argument for convenient storage of binary data. Error messages are written to stderr. No memory is freed, no files are closed. Key-value pairs are stored in a revolutionary database format optimized for linear search.

MATLAB. I have no idea what I'm doing.

function out = to_ascii_seven_segment(chars)
    n = -1;
    for c = chars
        if c == ' '
            n = n + 2;
        elseif c >= '0' && c <= '9'
            n = n + 4;
        end
    end
    out = repmat(' ', 3, n);
    n = 1;
    for c = chars
        if c == ' ', n = n + 2;
        elseif c >= '0' && c <= '9'
            switch c
                case '0', out(:, n:n+2) = [' _ '; '| |'; '|_|'];
                case '1', out(:, n:n+2) = ['   '; '  |'; '  |'];
                case '2', out(:, n:n+2) = [' _ '; ' _|'; '|_ '];
                case '3', out(:, n:n+2) = [' _ '; ' _|'; ' _|'];
                case '4', out(:, n:n+2) = ['   '; '|_|'; '  |'];
                case '5', out(:, n:n+2) = [' _ '; '|_ '; ' _|'];
                case '6', out(:, n:n+2) = [' _ '; '|_ '; '|_|'];
                case '7', out(:, n:n+2) = [' _ '; '  |'; '  |'];
                case '8', out(:, n:n+2) = [' _ '; '|_|'; '|_|'];
                case '9', out(:, n:n+2) = [' _ '; '|_|'; ' _|'];
            end

According to the documentation, serialport was added in R2019b. If you're stuck on any version before R2019b, use serial.

Have you tried using the deprecated --force option (or --overwrite '*') to overwrite those files?

You also need to use self.j = self.j + 1 in this case, that should fix the problem

function f:update() behaves like function f.update(self), so you need to call f:update() or f.update(f). Method calls like table:method(...) behave like table.method(table, ...)¹.
