数字信号处理程序——用FFT实现信号频谱分析的matlab程序(Digital signal processing procedures- implementation using FFT signal spectrum analysis matlab program)

在matlab中构成不同频率的调制信号，这些函数都是以fm开头，产生常数、双曲线、线性、抛物线等频率调制信号．(in Matlab, constitute a different frequency modulation signal, these functions are beginning to fm, have a constant, hyperbolic, linear, parabolic and other frequency-modulated signal.)

K均值有效执行++多元数据的聚类算法。它已经表明，该算法具有的总群集内距离的期望值是日志（K）的竞争力的上限。此外，K -均值++通常远高于香草收敛K均值少。(An efficient implementation of the k-means++ algorithm for clustering multivariate data. It has been shown that this algorithm has an upper bound for the expected value of the total intra-cluster distance which is log(k) competitive. Additionally, k-means++ usually converges in far fewer than vanilla k-means.)

新加入条件属性对决策属性的依赖度计算函数。基于粗糙集。(The new conditions for accession to the decision attribute attribute dependency calculation functions. Based on rough sets.)

Matlab 利用S函数编写系统模型，分为离散模型和非线性模型。(Matlab to using S functions to the preparation of system model, is divided into discrete model and nonlinear models are.)

车辆系统动力学单轮模型中非簧载质量变化对轮胎动载荷，悬架动行程，不舒适性参数的影响的源程序(Vehicle System Dynamics single wheel model non-sprung mass change dynamic load on the tire, suspension dynamic travel, not comfort parameters of the source)

我们做很多实验时得到的一些数字信号必须经过处理才能最终得到应用。此文件是matlab数字信号处理说明书，希望对读者有帮助(We do a lot of experiments to get some of the digital signal must be processed in order to ultimately be applied. This file is matlab digital signal processing instructions, hoping to help the reader)
