著名科学软件平台Matlab（矩阵实验室）早期1.0版本for DOS(Eminent scientific software platform Matlab (Matrix Laboratory) early version 1.0 for DOS)

这是一个MATLAB的IIR滤波器的程序!(This is a program of IIR fliter!)

自己写的用matlab读取YUV文件,并分帧保存.生成一个N维矩阵(N是总帧数),一维就是一帧的数据. Y U V分别保存.(wrote it myself using Matlab YUV read documents, preservation and framing. Generating an N-dimensional matrix (N is the total frame count). is a one-dimensional data. Y U V were preserved.)

BP神经网络算法MATLAB程序，神经网络在寻优方面的应用。(BP neural network algorithm MATLAB program, the application of neural network optimization.)

录制一段自己的语音信号，并对录制的信号进行采样；画出采样后语音信号的时域波形和频谱图；给定滤波器的性能指标，采用窗函数法和双线性变换设计滤波器，并画出滤波器的频率响应；然后用自己设计的滤波器对采集的信号进行滤波，画出滤波后信号的时域波形和频谱，并对滤波前后的信号进行对比，分析信号的变化；回放语音信号；最后，设计一个信号处理系统界面。(Section of their own voice recording signal, and recording the signal sampling draw sample after the speech signal time-domain waveform and frequency spectrum given filter performance indicators, using a window function method and bilinear transformation design of filters, and draw the frequency response filter then use the filter of their own design for the signal acquisition filtering, after filtering the signal to draw the time-domain waveform and spectrum, and filtering of signals before and after contrast, analysis of signal changes playback voice signal Finally, the design of a signal processing system interface.)

改进的基于区域的图像分割算法，对含有噪声的图像非常适用！在matlab6.5下顺利编译通过 (Improvement on the region's image segmentation algorithm for noisy images very well! In matlab6.5 smoothly through the compiler)

该程序是MATLAB环境下的小波消噪程序，自我感觉很有用，在此分享(The program is under the MATLAB environment, wavelet denoising process, feel useful, to share in this)
