本博客中输出版本号和日期的子函数，今天才发现忘记上代码了，这里补上

function banner()%% ------------------------------------------------------------------------%%            Output Info about matlab%fprintf('\n***********************************************************\n');[v, d] = version;fprintf('    MATLAB Version: %20s\n\n', v);fprintf('     Released Date: %17s\n\n', d);time_stamp = datestr(now, 31);[wkd1, wkd2] = weekday(today, 'long');fprintf('      Now is %20s, and it is %7s  \n\n', time_stamp, wkd2);%% ------------------------------------------------------------------------

　　运行效果如下：

       还有其它参数，具体可参考帮助文件。
