matlab扩展编程，介绍了matlab的新特性，常用的代码优化方法和功能扩展途径(matlab Extension programming )

此程序是描述的RSSI曲线的代码 重点与A值和n值的关系！(the relationship between the parameters of the n and A in RSSI)

Ensure the default values are set for any receiver, activity, service, etc. of Calendar.

说明：  异步电机的SVPWM闭环的DTCsimulink文件，可以闭环正常运行，波形还行(Asynchronous motor SVPWM closed-loop dtcsimulink file, can be closed-loop normal operation, waveform is OK)

神经网络LMS算法的学习规则，求的最大稳态学习速度，进行权值学习训练(artificial Neural Network Least Mean Square)

实用matlab进行l1性能指标下的滤波器设计，可以针对传递函数模型或者零极点模型。(Practical matlab to l1 performance under the filter design can be for the transfer function model or a model of zero-pole.)

Perform a local histogram equalization in matlab. No image processing toolbox is needed!

说明：  用于近红外光谱建模前，进行光谱预处理，一般与snv有类似作用(Model for near infrared spectroscopy before, spectral preprocessing, generally have a similar effect with snv)
