对实际采集的舰船辐射噪声进行了demo谱分析，分别采用了窄带解调和宽带解调两种方式，得到了较清晰的轴频和叶频信息。(use narrow-band and broad-band methods to demodulate the ship-radiated noise which is actually colleted, there can see clear axle frequency and blade frequency in the demo spectrum.)

说明：  包含马尔可夫预测、贝叶斯决策、模糊聚类分析、模糊综合评价方法等多种计算方法(Including Markov prediction, Bayesian decision-making, fuzzy clustering analysis, fuzzy comprehensive evaluation and other calculation methods)

poisson生成器，可以生成泊松分布的随机数，需要的就下载吧(poisson sasadas)

给定样本点，采用高斯核密度估计，求出概率密度分布函数。(It is good to use this method to evaluate pdf)

说明：  Amplitude of Explosion.In contrast to the design of sparks number, the am-plitude of a good firework explosion is smaller than that of a bad one. Amplitudeof explosion for each firework is defined as follows

适用于Engine计算的经典PISO算法(the classic PISO algorithm for the Engine calculation )

大型上用有限元软件ABAQUS的用户自定义材料子程序UMAT，用于计算材料低周疲劳极限和损伤下的应力应变关系(calculating material low cycle fatigue limit)

说明：  层次分析法：计算代码在8文件中最后一页上，有实例。(AHP)

这是另一个改进的关于数字预失真功能仿真的matlab程序，效果不错，希望对大家有所帮助。(This is a improved matlab program about function estimation of digital estimation,and it has a good performance,really hope it can help you.)
