fft的c++语言实现，改自matlab的相关程序(fft c++)

经典小波包分解，并计算各频带能量，能量比等参数(wavelet package decomposition and energy of frequency band)

脉冲群发生器,用于产生激励的触发脉冲群，也可用于干扰脉冲群产生(Burst generator, for generating a trigger pulse excitation group can also be used to generate the noise burst)

初学CS，自己编了很多算法，试试发出来大家一起交流，基于CS的OMP算法(OMP algorithm based on CS)

自己做的三相整流器，使用矢量控制。simulink的仿真平台做的，很强大哦(this is a three phase rectifier)

主路径信号的前导码，主要包含功能信号和基准时间信号。(The preamble of the main-path signal)

matlab环境下的前推后代法潮流计算程序，是7个节点的配电网。(before pushing sweep method flow calculation program matlab environment, the distribution network is seven nodes.)

Ethernet for PNX8935, PNX8932, PNX8335, PNX8332

近似熵是一种衡量衡量非线性时间序列复杂性的非线性动力学分析方法，其物理意义 为熵值越大，时间序列的自我相似性越低，序 列越复杂，反之序列自我相似性越高；并且样 本熵对于序列长度依赖弱，仅需较短的数据就 能够得到稳健的熵值，同时其计算不需对数据 粗粒化，具有较好的抗干扰能力 (Approximate entropy is a measure to measure the complex nonlinear dynamics of nonlinear time series analysis method, the physical meaning of entropy value is larger, the lower the self-similarity of the time series, the more complex the sequence, whereas sequence of self-similarity the higher and the sample entropy weak dependence for the length of the sequence, only shorter data can be healthy entropy value, calculated without data coarse-grained, with good anti-jamming capability)
