基于概率神经网络的柴油机故障诊断
- matlab下基于概率神经网络，对柴油机故障的一个简单诊断。(A simple diagnosis of diesel engine faults based on probabilistic neural network under Matlab is presented.)
OFDM
- 程序实现了OFDM通信系统的仿真，包括QPSK调制、串并转化、IFFT、并串转化、插入保护间隔AWGN信道传输以及逆过程(The program realizes the simulation of OFDM communication system, including QPSK modulation, serial-parallel conversion, IFFT, parallel-serial conversion, insertion protection interval AWGN
大气湍流模拟
- 大气湍流相位屏模拟举例，对研究激光大气传输有一定帮助(an example of phase screen which is helpful to the research of the transmit of laser)
nc4读取
- 用matlab实现读取.nc4格式影像NDVI为tif格式文件的实例，简单方便(Using MATLAB to read.Nc4 format image NDVI for TIF format files, simple and convenient)
MLE
- 用matlab实现基于正态分布的极大似然估计(Realization of maximum likelihood estimation based on normal distribution)
track_J2
- 考虑J2摄动的轨道预报，时间为tle中的时间格式(Orbital prediction considering J2 perturbation)
基于四阶累积量的MUSIC算法
- 基于四阶累积量的MUSIC多重信号分类算法源程序(MUSIC algorithms based on fourth - order cumulant)
cfar_detector2
- 雷达的恒虚警检测技术，二维cfar，采用十字形取数法(Radar CFAR detection technology, two-dimensional CFAR, using the cross number method)
dbscan
- DBSCAN(Density-Based Spatial Clustering of Applications with Noise)是一个比较有代表性的基于密度的聚类算法。与划分和层次聚类方法不同，它将簇定义为密度相连的点的最大集合，能够把具有足够高密度的区域划分为簇，并可在噪声的空间数据库中发现任意形状的聚类。(Classical clustering algorithm)
模态参数辨识
- 1）通过随机建立法处理振动响应信号，是时域数据模态辨识的预处理方法 2）通过有理多项式辨识模态参数(The random establishment method is used to deal with the vibration response signal, and it is a preprocessing method for the time domain data modal identification.)
小波分析
- 数学建模中常用到的算法，小波数值分析，有很高参考价值(The algorithms commonly used in mathematical modeling and wavelet numerical analysis have very high reference value.)
B-spline
- 均匀三次B样条曲线插值，定义插值函数，B样条拟合三维曲面(Interpolation of B spline curves)
