对仿真信号进行特征值分解，进行奇异值降噪处理(SVD Denoise)

傅里叶对干涉相位梯度进行变换，以执行一种新的加权最小二乘(Fourier transform on the interferometric phase gradient to perform a new weighted least squares)

二维哈尔小波变换,可以用来学习matlab对图像处理.(Second维哈尔wavelet transform, can be used to study matlab for image processing.)

计算一维向量的Renyi熵，已经设置为头文件，可以直接调用(One-dimensional vector of Renyi entropy, has been set for the header file, you can directly call)

说明：  梯度法是最优化方法中由于球多变量最优值的一种方法(Gradient method is the most optimal method of multi-variable optimal value due to the ball a way of)

基于matlab三角波的写法及改进的载波设计。(Based on the wording of the triangular wave Matlab and improved carrier design。)

首先通过自相关 偏自相关分析获得特征向量的维数，随后继续运行后面的代码以获得预测值,该方法为最近邻抽样回归预测(The dimension of feature vectors will be obtained by the autocorrelation and partial autocorrelation analysis, then continue to run the code behind to get predicted value，its short name is NNBR)

标准粒子群算法，改进粒子群算法，希望大家能用上(Standard particle swarm optimization, improved particle swarm algorithm, hope everyone can be on the)

说明：  matlab常用算法集，内含常用的各种数学函数。(matlab common set of algorithms, containing a variety of commonly used mathematical functions.)
