说明：  计算SSIM的matlab相关的代码,通过它可求两张图片的结构相似度(cal ssim,which can calculate the ssim between two images)

说明：  matlab读书笔记 matlab读书笔记(matlab Reading Notes matlab Reading Notes)

Here the syms toolbox is used and if you try to print any other values than lambda then MATLAB will print the value in fractions and that is unavoidable. So if you need to know the value in decimal, then use the command vpa() on command window

9/7提升小波的代码,用matlab写的,欢迎大家交流!(9/7 lifting wavelet code, written with matlab, welcomed the exchange of everyone!)

phase correlation - image matching(phase correlation- image matching)

利用kalman滤波器对具有随机加速度的物体运动路线的进行信号采样，滤波处理和估计。(use kalman filter to sample signals of object moving route with random acceleration,filter and estimate)

基于matlab的语音采集及滤波系统的仿真实现(Matlab voice-based filtering system acquisition and Simulation)

PLS - DN是一个有限的牛顿为解决非退化的分段线性系统的算法。 PLS - DN的展品可证明半迭代 财产即在全球范围内的精确解在有限数量的迭代算法收敛。被证明是收敛速度 至少前终止线性。 广泛的算法是在我们的AISTATS 2011纸描述：“一个非退化的分段线性系统的有限牛顿算法”。此演示包重新运行 在解决非负最小二乘法（NNLS）问题上的三个稀疏的设计矩阵，从哈威尔波音收集（达夫等人，1989年）第4.2节的实验。 随着PLS - DN，此演示包建议实施五 其他NNLS求解：LCP_Fisher_Newton，LCP_Lemke，PQN，TRESNEI，和SCD (PLS- DN is a finite non-degenerate Newton to solve the piecewise linear system algorithms. PLS- DN exhibits semi-iterative property to prove that the exact solutions worldwide in a limited number of iterative convergence. Proved to be terminated before the linear convergence rate at least. A wide range of algorithms in our AISTATS 2011 paper describes: " a non-degenerate sub-linear systems with limited Newton algorithm." This demo package to re-run in the settlement of non-negative least squares (NNLS) on the design of the three sparse matrices from the Harwell Boeing collection (Duff et al, 1989) Section 4.2 of the experiment. With PLS- DN, this demonstrates the implementation of five other NNLS package proposed solution: LCP_Fisher_Newton, LCP_Lemke, PQN, TRESNEI, and SCD)

利用MATLAB 仿真工具设计出一个QPSK仿真程序，以衡量QPSK在理想信道、高斯白噪声信道和先通过瑞利衰落信道再通过高斯信道三种方式的调制解调得到的功率谱密度、噪声曲线、星座图及误码性能,并对仿真结果进行了分析。(QPSK simulation design and Realization Based on MATLAB)

遗传算法优化BP神经网络，优化神经网络的初始权值和阈值(Genetic algorithm optimizes the BP neural network and optimizes the initial weights and thresholds of the neural network.)
