北斗导航系统与GPS组合在民航的应用

灰色理论的微分方程型模型称为GM模型，G表示grey(灰)，M表示Model(模型)．GM(1，N)表示1阶的，N个变量的微分方程型模型．而GM(1，1)则是1阶的， 1个变量的微分方程型模型。

心电信号QRS复波实时检测,软件主要是检测出R波波峰位置，采用双阈值法进行检测。配有GUI演示界面。所用数据为MIT，1986年心电数据库。此为医学信号处理实验课程作业，与大家分享

基于matlab仿真的非线性调频，此非线性调频利用s曲线生成调频函数，有较高的主副比，在信噪比的抑制方面有较好的性能

使用幂法求计算矩阵的主特征值及主特征向量，用反幂法求计算矩阵的按模最小特征值及特征向量。

用极限学习机分类，里面有完整的程序，欢迎前来下载，你值得拥有！一定完美运行，可以的话，欢迎好评。

采用Matlab编写的有限元方法，效果非常好
