很好的matlab作图word文档,希望对大家有帮助(Mapping matlab good word documents, and they hope to help everyone)

On the implementation and usage of SDPT3 – a Matlab software package for semidefinite-quadratic-linear programming, version 4.0

用脉冲响应不变法和双线性变换法设计数字带通滤波器(Impulse response using the same method and bilinear transformation method the number of band-pass filter design)

设计一个简单的GUI界面，对导入的音频文件进行时域特性分析。计算其时域波形、平均幅度、短时能量、短时过零率。对该音频文件进行加噪处理，分析其时域波形变化。设定一个固定时长，对该音频添加回声并保存为“*.wav”格式文件。 对音频文件的时域分析是对音频文件进行传输、降噪及其他再编辑的基础。其中短时能量可用作清浊音区分的标准和语音起始点的判断。短时过零率可用作判断有声段与无声段和从背景噪声中提取语音信号。 (Design a simple GUI interface that time domain characteristics analysis on import audio files.Calculate the average time domain waveform, amplitude, short-time energy and short-time zero crossing ratio.Add to deal with the noise of the audio files, analyze the changes in the time domain waveform.To set a fixed time, to add the audio echo and saved as a *. Wav format file. The time domain analysis of the audio file was transmitted to audio files, noise reduction and other editor again.The short-time energy voiced distinguish between standard and can be used as a clear voice starting point judgement.Short-time zero crossing ratio can be used as a judgment audio segment and silent segment and extract speech signal background noise.)

利用matlab开发的偏微分方程图形图像处理小程序，效果非常好，简单易用(using Matlab development of the PDE small graphic image processing procedures, the effect is very good, simple and easy)

实现测量学中的坐标正算功能，基于matlab进行了相关编程(The positive operator function coordinates Surveying related programming, based on matlab)

bpa环境下，Ieee39节点稳态暂态标准数据(the bpa environment IEEE 39 node Steady State Transient standard data)

采用PDA算法实现量测-航迹关联，常用于目标跟踪(Track association using PDA)

matlab实用程序，主要针对图像处理，二值化等(matlab utilities, mainly for image processing, binarization, etc.)

ofdm系统matlab仿真研究，结合书本觉得很有用。(Simulation of the system matlab OFDM, combine the book feel useful.)
