该段程序完成了由输入信号抽样值到pcm的编码过程.(The section of program completed by the input signal value to the pcm coding process.)

自己设计的新型FFT算法，用MATLAB仿真通过，绝对好用的源码。可以发论文。包括了FFT经典算法和改进算法的c实现(Designed a new type of FFT algorithm, through the use of MATLAB simulation, the source is absolutely easy to use. Papers can be made. Includes the classic FFT algorithm and improved algorithm for the realization of c)

说明：  MATLAB自适应辨识函数，相对比较简单，初学者很有用(Adaptive Identification MATLAB function is relatively simple, useful for beginners)

说明：  光斑聚集的C++程序调用，以前MATLAB计算要15分钟，现在只要3分钟就可以算完。运算超快。(Gathering spot called C++ program, MATLAB calculations to 15 minutes, now only 3 minutes. Ultrafast operation.)

基于递归神经网络模型的传感器非线性动态补偿，该资料是一篇文章，讲述了利用神经网络对传感器进行非线性动态补偿。(Based on recurrent neural network model nonlinear dynamic compensation sensor, the data is an article about the use of neural networks for sensor nonlinear dynamic compensation.)

This function takes the n time domain samples (real or complex) and finds the psd by taking (fft/n)^2. The two sided spectrum is produced by shifting the psd The array freq provides the appropriate frequency values for plotting purposes. By taking 10*log10(psd/max(psd)) the psd is normalized values beow 60db are set equal to -60db

四节点单元刚度矩阵，使用matlab编制，上传的是m文件。(QuadraticQuadElementStiffness，by matlab )
