本算法在实验室环境下录制语音，并加入matlab仿真软件产生的高斯噪声，成功实现了谱减法语音降噪(Record the voice of the algorithm in a laboratory environment, and added matlab simulation software generate Gaussian noise, the successful implementation of spectral subtraction speech noise reduction)

用matlab的编程实现一首歌曲的播放。歌曲是用代码编辑的，运行后就能实现播放。(Realization of a song to play using matlab programming. The song is in code editor, can be achieved after playing running.)

neural network based fault finding relay

non-local means filter 用于去噪，里面的矩阵操作编写的代码，速度比较快(non-local means filter for noise removal, inside the matrix manipulation code written faster)

Unscented Kalman Filter (UKF) exemplified on FitzHugh-Nagumo neuron dynamics. Voltage observed, currents and inputs estimated. FitzHughNagumo.m is the main program which calls the other programs. If you use these programs for your publications etc., please refer to H.U. Voss, J. Timmer & J. Kurths, Nonlinear dynamical system identification from uncertain and indirect measurements, Int. J. Bifurcation and Chaos 14, 1905-1933 (2004). I will be happy to email this paper, which contains a tutorial about estimation of hidden states and unscented Kalman filtering.
