说明：  一个matlab mex 文件，可以用来在matlab程序中捕捉用户按下的特殊功能健：F1, ..., F12. 使用时，在你的应用程序的 KeyPressFcn的函数体里，是用wgfcnkey，根据其返回值，判断是否有功能健被按下。(a Matlab mex documents, in Matlab can be used to capture user proceedings of the special features? Kin : F1, ..., F12. When used in your application's function KeyPressFcn the body, is wgfcnkey, return value, determine whether there is any function Kin is pressed.)

说明：  实现HDB3编码，HDB3码是AMI码的一种改进型，其目的是为保持AMI码的优点而克服其缺点，使连“0”个数不超过3个。(Achieve HDB3 encoding, HDB3 code is a modified AMI code, its purpose is to maintain the benefits of AMI code to overcome its shortcomings, so that even the &quot 0&quot the number of not more than 3.)
