HHTspe HHT谱计算程序，不是rilling版本，用改进的Hilbert变换(HHTspe HHT spectrum calculation program, not rilling version, using a modified Hilbert transform)

关于国内PH研究,其中包括ph值的预测控制，线性反馈，模糊控制等等(the lastest research of ph,and it contains MPC and linear control)

这是一个随机网络产生模型,可以用它仿真网络进行实验,程序采用matlab 语言编写(This is a random network generation model, the network can use simulation test, the program written by matlab)

matlab code for inertial navigation

一个关于图像边缘检测的实用程序-A practical program for image edge check(One on edge detection utility-A practical program for image edge check)

一种时频变换方法—Margenau-Hil分布，用于信号时频分析。(A time-frequency transformation method-Margenau-Hil distribution for the signal time-frequency analysis.)

BER performance in flat fading channels using bpsk modulation

说明：  离散信号Gabor展开的理论及实现颇为繁琐。其中包括离散Gabor变换的标架理论、周期序列的离散Gabor变换、非周期序列的离散Gabor变换以及各种快速算法等。此程序给出给出了一个线性调频信号的Gabor变换。(Gabor expansion of discrete signals and the realization of the theory is quite cumbersome. Including discrete Gabor transform frame theory, the periodic sequence of discrete Gabor transform, non-periodic sequence of discrete Gabor transform and a variety of fast algorithms. This procedure gives a linear FM signal is given the Gabor transform.)

说明：  一个动画模拟的粒子寻找最小值的一个简单程序，有助于学习粒子群法(an animated simulation of particles searching for the minima of a simple function，which helps you learn PSO. )

利用MATLAB绘制等温线，以湖南省为例，绘制了省界，97县的位置以及等温线。(plot temperature contour through MATLAB.)
