在matlab中可以调用的程序，用c语言编写，cuda求直方图(used in caculating histogram of color images , )

FDTD code of a 2-D rectangular waveguide with Berenger s PML termination

在瑞利信道条件下采用差分调制，LDPC编码系统的BP译码算法的实现。(Differential modulation in Rayleigh channel conditions, achieve BP decoding algorithm for LDPC coding system.)

说明：  随着信息容量的增加和频率资源的稀缺，为提高单位频带利用率，在微波通信系统中越来越多地采用多电平多相位的复杂信号调制方式，尤其是正交幅度调制(QAM)得到了大量的应用，从早期的4QAM到今天的16QAM。高阶QAM调制大容量数字微波通信系统为了保证服务质量，降低误码率，(long with the increase of information capacity and frequency resource scarcity, for improving the utilization ratio, unit of microwave communication bandwidth used more and more in the system of multilevel much phase modulation method complex signal amplitude modulation )

利用matlab的simulink进行三杆的工作空间仿真分析(The use of matlab simulink for three working space simulation analysis)

对列车平稳性实验数据处理的MATLAB程序代码，涉及文件导入，时域图像绘制，数据处理，傅里叶变换，频域图像绘制，平稳性指标计算(I can t speak English.)

program for autocorelation

To find and estimate of the best solution and parameter in our problem we can use the evolutionary programming. PSO (particle swarm optimization) is an applicable method to catch this target. In these files I show the Simple PSO that it can be base of solve complicated problem, the code could run by MATLAB.
