: 针对实际振动位移难以获取的问题, 利用振动位移与加速度信号之间的关系, 先对采样后的加速度信 号采用时域数值积分,得到含有趋势项的速度信号及位移信号,再采用拟合多项式极值的方法, 消除积分过程 中产生的趋势项,从而得到更为精确的速度和位移信号. 算例表明, 利用拟合多项式极值消除趋势项的方法, 得到的位移时程曲线拟合精度高(: In pract ical engineering , the collection of displacement data is mo re dif ficult than that of the acceleratio n data in the time-domain .Displacement sig nals w as g ot f rom acceleration s ignals using aumerical integrat ion , wi th the t rend o f erro r.

全息故障诊断中的时频谱图，轴心轨迹等matlab程序代码，故诊断必学(matlab code for fault diagonis)

该程序对ofdm系统中mmsnr的信道缩短算法的误码率性率进行了仿真，而且与没有信道缩短的只加cp的ofdm的系统进行了对比.程序包可以完整实现仿真，并得到理想的效果图，相信对做信道时域均衡的人会有所帮助！(ofdm mssnr TEQ equlization)

自动控制方面的MATLAB程序，PID控制(Automatic control of MATLAB, PID control)

function [L,C] = kmeans(X,k) KMEANS Cluster multivariate data using the k-means++ algorithm. [L,C] = kmeans(X,k) produces a 1-by-size(X,2) vector L with one class label per column in X and a size(X,1)-by-k matrix C containing the centers corresponding to each class.
