说明：  matlab中字符识别时，列分割和行分割字符的代码！根据一位网友上传的行分割字符改的！回馈吧友！ 亲测有效，列分割比较好，行分割效果有点小问题。希望改进的亲提出意见！声明：这个分割用的算法比较简单，所以适用于字符间隙比较宽，字符比较规范的情况。手写或者字符挨得太近可能会出错！
(When recognizing characters in matlab, the code of column segmentation and row segmentation characters! Pro-test is effective, column segmentation is better, row segmentation is a little bit of a problem. Hope to improve the pro-comments! Declarations: This segmentation algorithm is relatively simple, so it is suitable for the case of wide character gap and standardized character. Handwriting or characters that are too close together can go wrong!)
