uncodeded block simulation with matlab

平面控制网平差程序，使用平面控制网测量数据进行最小二乘法平差拟合，得到平面控制网结果(use of TSL and surveying datas to get horizontal control network result)

说明：  提出了一种改进高阶Butterworth低通滤波器性能的设计方法。首先对高阶Butterworth低通滤波器的极点 进行重新分布，得出改进型Butterworth低通滤波器。性可以由其在基波电压初相位为零时的特性所唯一确定(Periodic voltage and current waveforms on the start time of its corresponding harmonic component of the relationship between the initial phase of research, pointed out that the characteristics of harmonic sources can be its initial phase in the fundamental zero-voltage characteristics of the CD a definite)

数字图像处理MATLAB演示程序。包含图像灰度处理、平滑、锐化、压缩等。运行demo.m执行主界面。(Digital Image Processing MATLAB demonstration program. Contains the image gray scale processing, smoothing, sharpening, compression. The run demo.m perform the main interface.)

matlab做的，关于滚动轴承振动信号故障诊断很重要的数据库，做机器学习的朋友可以看看啊！(Matlab do, on the rolling bearing vibration signal fault diagnosis is very important , machine learning friends can see ah!)

说明：  根据采样定理编写程序,实现模拟信号的采样,画出采样波形.(According to sampling theorem, programming, analog signal sampling, draw sample waveform.)

流形学习是一种新的无监督机器学习方法，局部线形嵌入（Locally Linear Embedding，LLE）发现嵌入在高维数据中的低维流形，流形学习算法,MATLAB程序(manifold learning)

Face Recognition By PCA using SVD technique .

程序仿真了瑞利信道，分析和大量实测表明，多径效应使接收信号包络变化接近瑞利分布。在典型移动通信中，衰落深度达30dB左右，衰落速率约30~40次/秒。(Rayleigh channel simulation procedures, analysis and extensive test shows that the received signal multipath effect changes in the envelope close to the Rayleigh distribution. In a typical mobile communication, fading depth of about 30dB, the decline rate of about 30 to 40 times/sec.)

MATLAB的MLR算法，希望对同学的学习有帮助(mlr MATLAB algorithm, very useful, I hope to learn some help)
