UFLDL教程softmaxt回归章节后面练习的答案，根据书上步骤在源码基础上修改而成(UFLDL tutorial exercises softmaxt return later chapters answer, according to the book steps to modify the source code is made on the basis of)

利用wolfe算法，编写了wolfe程序模块。测试数据引用《最优化方法及其Matlab程序设计》(马昌凤编)的Armijo准则搜索例题(Use wolfe algorithm, written wolfe program modules. Test data reference " optimization methods and Matlab programming" (Ma Changfeng ed.) The search criteria examples Armijo)

利用music方法来进行doa估计，常用于阵列信号处理中(The use of music means to carry out doa estimation, commonly used in array signal processing in)

说明：  此程序为语音信号的过零率检测，白噪声过零率远远高于语音信号，故可通过对过零率的检测判断出是不是语音信号。(This procedure for the zero rate of speech signal detection, white noise zero crossing rate is much higher than the speech signal, it can zero rate by detection of voice signal is not judged.)

说明：  本程序适用于解决故障检测，数据驱动问题，主要应用pls.(This procedure applies to solve the fault detection, data-driven problems, the main application pls.)

matlab方面有很多程序可以使用到学习与工作中(matlab, there are many programs you can use to learn and work)

An electric meters are used everywhere to calculate the consumption of power. Wireless meter reading technology can save human resources and another feature of this kind of meter is, it improve the accuracy since it works on real time application, enabling management sector to access to data messages within a short period of time and accurately. Due to its wireless communication network, it just not save human and material resources but this property leads to most economical meter in terms of investment. In this paper, power consumed by the consumer is monitored by base stations through wireless network. It aims to reduce the man power for billing since the meter reading is transmitted through ZigBee and at base stations we calculate bill, save records of consumers. The most important part of this project is that we can monitor any fault in meter as well as any tempering which is used to steal the electricity.

经验模态分解代码，依据数据自身的时间尺度特征来进行信号分解，无须预先设定任何基函数。(Empirical mode decomposition code, based on the data of their characteristic time scale for signal decomposition, no need of any of a set of basis function.)
