This program is used to do optimisation for multidimension system, SIMPLEX method for multidimensional unconstrained non-linear optimsiation (This program is used to do optimisation for multidimension system, SIMPLEX method for multidimensional unconstrained non-linear optimsiation)

安捷仑的数字调制信号发生器E4438用于很多通信系统的开发过程中。本代码可以用于通过网络接口或GPIB接口向E4438下载被调制数据(Ansett in 2000 digital modulation signal generator E4438 used in many communications systems development process. The code can be used by the network interface or E4438 GPIB interface to download data to be modulated)

根据电缆长度计算电缆短路电流。写的不是非常好(Calculation of cable short circuit current according to the length of the cable.)

his is a simple method for silence removal and segmentation of audio streams that contain speech. The method is based in two simple audio features (signal energy and spectral centroid). As long as the feature sequences are extracted, as thresholding approach is applied on those sequence, in order to detect the speech segment

计算机控制工程中数字PID用ISTE方法整定matlab的实现算法(Computer control works in digital tuning PID ISTE method matlab realization algorithm)

说明：  一种核密度估计，或者称作带宽选择的方法，可以估计二维尺度参数，至于多维以上的估计方法尚在开发，多维情况下个人经验好的方法是多次实验取较好值(kernel density estimation, bandwidth selection, two-dimensional scale parameter can be estimated ,for the multi-dimensional approaches are still under development, multi-dimensional cases, personal experience is to do the experiment many times)

说明：  BP算法的批处理，并且实现“异或”功能。(BP algorithm)

消除50Hz工频干扰数字滤波器的设计,设计思路很巧妙，程序很小很好用(Eliminate the 50Hz frequency interference digital filter design, design ideas is very clever, good program is very small)

用M文件控制Matlab/Simulink模块里的变量和计算过程。(This code use M-file to control some varible and calculation flow of Matlab/Simulink blocks.)
