利用矩阵进行坐标系转换(转)



转自:http://www.cnblogs.com/ILove/archive/2009/06/23/1509607.html之前做拓扑图,本来打算整一套坐标系统在里面的,后来因为时间原因暂时用了最原始的方法实现。现在稍稍得闲,重新开始思考这个问题。不过在搜索的时候,意外发现.Net Framework类库中自带的有实现坐标系转换功能的类。Reflector了一把,发现代码看不懂了——都是利用矩阵...

使用Word尾注实现论文参考文献自动排序的方法(转)

转自:https://www.douban.com/note/208819555/ Word中插入尾注的功能很好地解决了在论文中按顺序插入参考文献的问题,可以方便地进行增删和重新排序。具体步骤如下:1.光标移到要插入参考文献的地方,菜单中“插入”——“脚注和尾注”。2.对话框中选择“尾注”,所在位置建议选“节的结尾”,编号格式为“1,2,3”。3.确定后在该处就插入了一个上标“1”,而光标自动跳到...

Dynamic Time Warping 动态时间规整算法(转)



转自:http://www.cnblogs.com/luxiaoxun/archive/2013/05/09/3069036.htmlDynamic Time Warping(DTW)是一种衡量两个时间序列之间的相似度的方法,主要应用在语音识别领域来识别两段语音是否表示同一个单词。1. DTW方法原理在时间序列中,需要比较相似性的两段时间序列的长度可能并不相等,在语音识别领域表现为不同人的语速不同...
