说明：  均匀圆阵波束形成，一个干扰情况下的自适应波束形成；双干扰下的均匀线阵波束形成(Uniform circular array beamforming, interference under an adaptive beamforming)

文件为关于如何用matlab进行编程的资料，用matlab编程比用C语言更容易，它的矩阵运算能力更是c语言难以比拟的。再用matlab编程时，一些小细节忘了可以看一下此文件。(Document on how to use matlab to program information with the matlab programming language more easily than C, its capacity is c matrix operations can not match the language. Then matlab programming, forgot some small details can look at this file.)

matlab对一幅图像，采用半径值为20、80、200的截止频率进行理想低通滤波，观察其结果。要求给出原图像及相应的付利叶频谱图和滤波结果(For an image, using the radius value of the cutoff frequency 20,80,200 ideal low-pass filter to observe the results. Required to give the original image and the corresponding Fourier spectrum and filtering results)

包含两个部分：1传统粒子群算法优化BP神经网络 2改进的粒子群算法优化BP神经网络源代码(It consists of two parts: a traditional particle swarm optimization BP neural network 2 Improved particle swarm optimization BP neural network source code)

反射系数与地震子波褶积合成地震记录，p，d，s分别是预设地层纵波速度、密度、及横波速度模型。其中包含可以改变主频的ricker子波，avopp是提取反射系数的程序。wigb可以对其中的多道进行强化显示。(Reflection coefficient and the convolution synthetic seismogram, the seismic wavelet p, d, s are preset formation p-wave velocity, density, and shear wave velocity model. Contains can change the frequency of the ricker wavelet, avopp is the process of the extraction of reflection coefficients. Wigb can to strengthen the multi-channel display.)
