本代码是针对《合成孔径雷达成像：算法与实现》书后光盘的CSA实现(This code is for " synthetic aperture radar imaging: algorithm and implementation," the book the disc to achieve CSA)

matlab应用实例，对于一个电路图，应用matlab仿真解题，求出电路某支路电流及波形(matlab application example, a circuit diagram for the application of problem-solving matlab simulation, find a branch circuit current and waveform)

PSO算法简单、易实现、计算量小，而且PSO 对初始点依赖性不大，具有更强的全局优化能力，也能较快的的收敛于可接受解。这是改进的pso,请多多指教。(PSO algorithm is simple, easy to realize the advantages of a small amount of computation and computational efficiency, and PSO dependence of the initial point, with stronger global optimization capability, but also faster convergence to an acceptable solution. This improved pso, exhibitions)

说明：  双闭环buck变换器模型，matlab simulink 仿真(Double closed loop buck converter model)

这是一个matlab的bp网络程序，可用于逼近和预测，程序里有详细的说明与注释，包括数据预处理、建立网络、训练、仿真、预测的整个过程。(This is a matlab the bp network procedures, can be used for approximation and prediction, procedure, there are detailed instructions and notes, including data pre-processing, networking, training, simulation, prediction of the whole process.)

Matlab C-C++ Graphics Library User s Guide

全面地介绍了数据建模的原理，内部有matalb代码和实现过程，是本很好的数学建模的书。(Comprehensive introduction to the principles of data modeling, internal matalb code and implementation process is the mathematical modeling of the good book.)

matlab下载用到的激活文件，实在不知道怎么藐视(matlab download activation files used, it is not to know how contempt)

此程序是计算电力系统潮流的通解，通过支路法不断更新参数(This procedure is the general solution of the power flow calculation, continuously updated through the branch method parameters)

对图像进行滤波、加噪，对图像进行模糊、复原处理，另有点扩散函数与光学转换函数间的互化。(The image is filtered and noisy, the image is blurred and restored, and the point diffusion function is interchanged with the optical conversion function.)
