amplitude modulation system using simulink matlab

这个是在matlab 中实现心电信号的读取和陷波器去除噪声，希望对大家能有帮助(this is a example for ECG designed in matlab,which including reading ECG and removing noise from ECG)

Mining quantitative association rules is one of the most important tasks in data mining and exists in many real-world problems. Many researches have proved that particle swarm optimization(PSO) algorithm is suitable for quantitative association rule mining (ARM) and there aremany successful cases in different fields. However, the method becomes inefficient even unavailable on huge datasets. This paper proposes a parallel PSO for quantitative association rule mining(PPQAR). The parallel algorithm designs two methods, particle-oriented and data-oriented parallelization, to fit different application scenarios. Experiments were conducted to evaluate these two methods. Results show that particle-oriented parallelization has a higher speedup, and dataoriented method is more general on large datasets.

本程序为坐标转换matlab程序，高斯正算即经纬度（L，B）转换为平面坐标（x，y），高斯反算反之。本程序的特点为完全适合多种参考椭球（即北京54坐标 西安80坐标 wgs84坐标 以及现阶段国家大力推行的cs2000坐标），转换精度达到亚毫米级，完全可以达到高精度坐标转换作业的要求。程序中使用矩阵实现了多点同时转换的能力，学习者也可以将其开发为自己坐标转换软件。
