提高MATLAB程序运行效率的方法大全。(A gathering of methods to shorten the processing time in MATLAB. )

This is a our final year project that we did for for the partial fulfillment of BSc degree in Electrical Engineering.

DCT变换：变换域系数选取采用阈值编码，：阈值越小，图像恢复效果越好，但压缩效果差，一般取在5-10 即可很好的获得恢复图像信息。(DCT transform: transform domain coefficients selected using the threshold coding: the smaller the threshold value, the better the image restoration, but the compression is poor, and generally in the 5-10 to get a good recovery image information.)

用matlab实现了指纹的预处理以及特征点的提取。(Using matlab fingerprint preprocessing and feature point extraction.)

语音信号处理，均衡播放，说话者语音识别，加速播放以及回音音效(Speech signal processing, balanced play, speaker voice recognition, accelerated playback as well as echo sound)

两个传感器进行串联形式连接，融合系统贝叶斯风险曲线以及ROC曲线(Two sensors are connected in series, as well as fusion system Bayesian risk curve ROC curve)

经典谱估计-周期图法 实现正弦波加正态白噪声信号的谱估计(Classical spectrum estimation- the realization of periodogram normal sine wave plus white noise signal spectrum estimation)

P and M class PMU examples for MATLAB

该代码为分布式MIMO天线选择的最优算法，递增算法，递减算法以及基于范数的算法。(The code for the Distributed MIMO antenna selection of the optimal algorithm, incremental algorithm, descending algorithm and norm-based algorithm.)

说明：  完全自主实现的神经网络代码，对于深刻理解神经网络和BP算法很有帮助。(The neural network code, which is implemented autonomously, is very helpful for us to deeply understand the neural network and BP algorithm.)
