对认知无线电的仿真程序，使用simulink进行仿真(On cognitive radio simulation program, using simulink simulation)

说明：  基于Matlab的函数优化遗传算法程序,包含了遗传算法实现的大部分步骤，而且有详细的注释.(Matlab functions genetic algorithm optimization procedures, including the genetic algorithm to achieve the most steps, and detailed notes.)

平面梁单元计算两铰抛物线拱的自由振动特性 采用平面梁单元计算两铰抛物线拱的自由振动特性 (Plane beam element calculation of the free vibration characteristics of two hinged parabolic arch)

matlab时间序列分析，是进行matlab学习与研究进行的很好的东西，适合初学者学习(matlab time series analysis, is a good thing matlab learning and research, for beginners to learn)

是matlab产生一个高斯脉冲的程序，并且叠加了高斯噪声，可以画出输入与输出的图形，并且对其时延进行了估计(Is the matlab produce a gaussian pulse program, and stack the gaussian noise, can draw the input and output of the graphics, and the time delay were estimated )

粒子群反演算法，可用于波动反演，地震领域，岩石破裂领域。(Particle swarm inversion algorithm can be used in wave inversion, seismic field, rock fracture field.)

使用Matlab对图片进行操作时，大量的单张图片不利于操作，此时需要将图片转化为.mat格式，.mat方便我们对数据的处理，使我们更加高效的利用数据。文章中的代码是以PIE数据集作为转换的原始数据，每张图片的名称是连续的数字，相同类别的图片张数相等且名称连续。(When using MATLAB to operate pictures, a large number of single pictures are not conducive to operation. At this time, we need to convert pictures into. mat format. mat is convenient for us to process data, so that we can use data more efficiently. The code in this article is PIE data set as the original data for conversion. The name of each picture is a continuous number. The number of pictures of the same category is equal and the name is continuous.)

在matlab环境先应用编程实现PFD的功能，并对其进行分析。(MATLAB PFD desire)
