matlab的一些文件，很好的东西哦，希望对大家有助。(matlab some documents, good things Oh, I hope to help everyone.)

基于角谱法的压缩全息仿真程序，内含有仿真调用的子程序：前向模型，反向模型，迭代优化等(compressive holography based on the angular spectrum method，including：forward propagating，backpropagating，Twist and so on)

it includes gammatone filters and cochlegram

HERE I HAD ATTACHED THE CODES FOR COMPRESSION

是一种双隐层反向传播神经网络，窗函数法设计一个数字带通FIR滤波器，采用的是通用的平面波展开法。( Is a two hidden layer back propagation neural network, A window function design FIR digital band-pass filter, Using common plane wave expansion method.)

非线性光学晶体KTP的1064nm的OPO频率变化计算(OPO nonlinear optical crystal KTP frequency of 1064nm calculation)

主要用于实现雷达信号的处理，对四目标进行识别测速(Mainly used to implement the processing of radar signals for the four target recognition speed)

利用相关的瞬时值通过在工作过程中的逐步调整参数逼近信号的统计特性，实现最优滤波。由此，我们得到一种最常用的算法——最小均方算法，简称LMS算法。(By using the instantaneous value of the correlation operation of the progressive approximation of the statistical properties of the signal to adjust the parameters to achieve optimal filtering. Thus, we get one of the most commonly used algorithms- the minimum mean square algorithm, called LMS algorithm.)
