本程序设计了常用的几个坐标系的转换，从WGS—84与PZ－90坐标系的相互转换，以及空间直角坐标系与大地坐标系的转换。(This procedure has designed a number of commonly used coordinate system conversion from WGS-84 and PZ-90 coordinate system conversion, as well as the spatial Cartesian coordinate system and geodetic coordinate system conversion.)

说明：  对粒子滤波算法的原理和应用进行综述’首先针对非线性非高斯系统的状态滤波问题C阐述粒子滤波的原理D然后在分析采样=重要性=重采样算法基础上C讨论粒子滤波算法存在的主要问题和改进手段D最后从概率密度函数的角度出发C将粒子滤波方法与其他非线性滤波算法进行比较C阐明了粒子滤波的适应性C给出了粒子滤波在一些研究领域中的应用C并展望了其未来发展方向(QJPRQ Elc8&m :jelf dgwd99&jvdej gq:c&decwe 9d:ejv&chj&ec:d:cqi:pcrcw’8jfjgmdeelcg g&jgcd:"g g= #diqqjdghj&ec:9: u&cfCelcmcgc:jvjwcdq h9d:ejv&chj&ec:d:cmjpcgCudqcwgelcdgd&rqjqhqedgwd:wd&m :jelf=jf9 :edgvc=:cqdf9&jgmhj&ec:Celc9h9d:ev&chj&ec:d:cwjqviqqcwdgwqcjf9:d:cj&&iqe:decw)

sampencandApEn.m 为证明 样本熵 较 近似熵 更准确的程序 fast_ApEn1.m sampenc.m 为sampencandApEn.m的子程序(sampencandApEn.m sample entropy to prove more accurate than the approximate entropy procedure 3.fast_ApEn1.m sampenc.m subroutine is sampencandApEn.m)

matlab程序将传递函数通过Z变换使其离散化，然后再把得到的脉冲传递函数改写成差分方程。便于接下来一步的C程序编程。(matlab program will transfer function Z-transform them through discrete, then put the resulting pulse transfer function of a differential equation rewritten. Facilitate the next step of the C programming.)

说明：  进行数据的预处理，标准化和白化，便于数据的后续分析(Data preprocessing, standardization and whitening, facilitate the subsequent analysis of data)

说明：  一个长信号进行分析时，可能需要对信号分段，本程序提供一种分段方法(When a long signal is analyzed, it may be necessary to segment the signal)
