求解双heilder雷电流的微分，该电流为雷电电磁模式常用的继后回击电流，对于模式研究具有重要意义(Solving the differential double heilder lightning current, the current model used for the electromagnetic lightning subsequent return stroke current study has important significance for the mode)

合流超几何函数是处理较为复杂的语音处理算法中的较为常见的程序，它在MATLAB中能够正确实现相对有些困难，附上的程序能够在语音增强算法中正确运行。(Confluent hypergeometric function is dealing with more complex voice processing algorithms in the more common procedures, it can be correctly implemented in MATLAB relatively somewhat difficult, enclosed in a speech enhancement algorithm program can run correctly.)

摘要:经验模态分解方法(EMD )在非平稳信号的分析和处理中起着重要的作用 ,为了能够方便的使用EMD方法对信号进行处理 ,现labVIEW 虚拟仪器开发平台良好的用户图形界面和TLAB 软件强大的数值分析功能相结合 ,利用 Lab V IEW调用 MATLAB实现EMD信号处理方法.仿真结果表明对信号进行EMD分解后,使得瞬时频率具有了物理意义,但只是对信号进行了初步处理 ,可根据实际需要进行相应后续处理 。(Abstract: The empirical mode decomposition (EMD) plays in the analysis and processing of non-stationary signals an important role, in order to facilitate the use of EMD method for signal processing, virtual instrument development platform now labVIEW good graphical user interface and TLAB powerful numerical analysis software combined with the use of Lab V IEW call MATLAB realize EMD signal processing methods. simulation results show that the signal EMD decomposition, so that the instantaneous frequency has a physical sense, but only a preliminary processing of the signal, according to The actual need for appropriate follow-up treatment.)
