描述倒立摆的仿真图，采用模糊控制的算法和最优控制策略。(The simulation diagram describing the inverted pendulum, fuzzy control algorithm and the optimal control strategy.)

source code using principal component analysis and similirity matching with the ecludien distance this is an approach used for face recognition. this file also contains and test images

It includes coding for walsh code encoding in matlab.The Walsh functions can be generated (or computed) by many methods. We can construct the Walsh functions by: • Using Hadamard matrices • Exploiting the symmetry properties of Walsh functions themselves. • The Hadamard matrix is a square array of plus and minus ones, {+1, -1}, whose rows and columns are mutually orthogonal

1．产生一个连续信号，包含低频，中频，高频分量，对其进行采样，进行频谱分析，分别设计三种高通， 低通，带通滤波器对信号进行滤波处理，观察滤波后信号的频谱。 2.采集一段含有噪音的语音信号（可以录制含有噪音的信号，或者录制语音后再加进噪音信号），对其进行 采样和频谱分析，根据分析结果设计出一合适的滤波器滤除噪音信号(1. Produce a continuous signal, including low-frequency, medium frequency, high-frequency components, its sampling, spectral analysis, are designed for three high-pass, low pass, band-pass filter the signal filtering treatment to observe the signal spectrum after filtering. 2. Acquisition section of the speech signal contains noise (can record a signal containing noise, or voice recording, additional noise after the signal), its sampling and spectral analysis, based on an analysis of the results to design a suitable filter to filter out one noise signal)

RAYTRACING, by itself, creates a new RAYTRACING or raises the existing singleton

说明：  高斯信道和噪声产生方法的简单程序，直接解压无密码(Gaussian noise channels and formation of simple procedures, without directly extracting passwords)

用于算法模糊分类，对于时间序列的聚类分析有较高的利用价值(Algorithm for fuzzy classification, clustering analysis of time series for a higher use value)
