This script will attempt to find the band gaps in a phononic crystal by carrying out a Plane Wave Expansion of the various quantities using square array method. There are 2 programs, one for short and the other one is for acoustic long

matlab下，用dspbuilder实现dds模块产生正弦波的源码(matlab under dds with the realization of dspbuilder generated sine wave source modules)

说明：  正交优化代码 两条相交线的优化matlab程序 (the code of youhua )

在matlab中采用haar小波实现的图像小波分解程序。(Matlab haar wavelet used in the realization of the image wavelet decomposition process.)

this is used for pv array grid connected system

说明：  图4.7给出了V=4，相位集合的相位数分别为P=1、2、4、8时的随机分割的PTS-OFDM系统的CCDF的性能图。仿真参数：分割方法为随机分割，子载波数N=128，子载波数据采用QPSK调制，仿真的OFDM符号数为1000个。(Figure 4.7 shows the V = 4, the phase of the collection phase, respectively P = 1,2,4,8 were separated when the PTS-OFDM system performance CCDF graph. Simulation parameters: Segmentation of random division, the number of subcarriers N = 128, sub-carrier data using QPSK modulation, simulation of the OFDM symbol number 1000.)

netCDF 文件读取工具，用于matlab，可以很方便的读取NetCDF文件中的信息(NetCDF tools for matlab)

相干信号的DOA估计，前后向平滑算法和差分平滑算法对比研究，有均方根的对比(DOA estimation of coherent signals before and after the smoothing algorithm and a comparative study of differential smoothing algorithm, RMS contrast)

gcc and gnu compilers
