马赫筛选器和光流的 MATLAB 代码

smith chart用于微波和电磁波分析和计算，在通讯工程中有良好的应用。(smith chart used for analysis and calculation of microwave and electromagnetic waves in communication engineering has a good application.)

此代码主要基于MATLAB平台完成，通过PSO算法优化RBFNN的权阀值，以实现对Ackley非线性系统的求解，再具体的应用中，通过归一化数据、划分训练集与测试集样本，实现了对二维Ackley问题极小值的精确求解，还从绝对误差与相对误差等角度综合对比了优化前后的差别。

基于RA准则的多用户OFDM自适应资源分配算法改进，速率自适应算法的分析，对于自适应算法研究的朋友很有帮助(RA-based criteria for adaptive multi-user OFDM resource allocation algorithm for improved analysis of the rate adaptive algorithm, adaptive algorithm for friends helpful)

精通matlab图像处理的配套光盘内有2-5章的程序代码(matlab，image process)

It is a team project for stress and deformation analysis

首先对图像进行边缘检测，利用连同区域提取出检测出的点的坐标，在用直接最小二乘法进行拟合，得到椭圆的5个参数，画出椭圆。

自己编的一个chase算法的小程序，只进行了一次迭代运算，关于多次迭代计算需进一步研究(developed an algorithm for small chase procedures, only a iteration, on the number of iterative calculations required further study)

wsn  is having an increasing success in the scientific, logistical, and military areas. It not only realizes benefits for the customer in a technologically sophisticated way, but in addition provides this with high flexibility. However, the size of the sensors is an important limitation, mainly in terms of energy.
