《最优阵列处理》一书第六章的MATLAB例程，包括各种最优波束形成算法的仿真。(" Optimal array processing," the sixth chapter of a book of MATLAB routines, including the optimal beamforming simulation algorithm.)

灰度图转换，可以把彩色图片转换为灰度图片。并进行计算(Grayscale conversion, color images can be converted to gray-scale image. And calculated)

说明：  基于matlab 的chan算法不加角度(Matlab-based algorithm for the chan no angle)

直接序列扩频就是直接用具有高码率的扩频码序列在发端去扩展信号的频谱。而在收端，用相同的扩频码序列去进行解扩还原成原始的信息。(Direct Sequence Spread Spectrum is the direct use of the spreading code sequence with a high rate in the originator to expand the spectrum of the signal. Receiving end, using the same spreading code sequence to despread the broadening of the spread spectrum signal to restore the original information.)

matlab画三个纵坐标源码,源码中有三维纵坐标的例子。(matlab draw three ordinate source, the source code is an example of a three-dimensional ordinate.)

Modulation of signal like amplitude modulation

该程序可用于神经网络变量筛选， BP神经网络，程序完整，可直接运行(Neural network variable filter, BP neural network)

to define color of the image

该代码是对人脸进行光照处理，先进行gamma变换，然后进行Dog双边滤波，然后进行灰度亮度的均衡。该方法能够有效提高光照变化的情况下的系统识别性能(The code is the human face of light treatment, the first for gamma conversion, and then Dog bilateral filtering, then the brightness of the gray balance. The method can effectively improve the illumination changes in the case of system identification performance)
