matlab符号表达式、符号矩阵的创建、符号线性代数因式分解、展开和简化符号代数方程求解、符号微积分符号微分方程(matlab symbolic expression, the creation of the matrix symbol, symbols, linear algebra factorization, and simplification of symbolic start to solve algebraic equations, symbols, symbol differential calculus)

数学建模中的常用算法及其在matlab中的应用，对于学习数学建模很有用。(Used in the mathematical modeling algorithm and its application in matlab useful for learning mathematical modeling.)

是一个自适应滤波器程序，用matlab编写，简单易用，大家试试哦(Is an adaptive filter program, written in matlab, easy to use, you try oh )

说明：  一个双向LSTM程序 Long Short Term 网络—— 一般就叫做 LSTM ——是一种 RNN 特殊的类型，可以学习长期依赖信息。LSTM 由Hochreiter & Schmidhuber (1997)提出，并在近期被Alex Graves进行了改良和推广。在很多问题，LSTM 都取得相当巨大的成功，并得到了广泛的使用。 LSTM 通过刻意的设计来避免长期依赖问题。记住长期的信息在实践中是 LSTM 的默认行为，而非需要付出很大代价才能获得的能力！ 所有 RNN 都具有一种重复神经网络模块的链式的形式。在标准的 RNN 中，这个重复的模块只有一个非常简单的结构，例如一个 tanh 层。(A bidirectional LSTM program Long short term network, commonly known as LSTM, is a special type of RNN that can learn long-term dependent information. LSTM was proposed by Hochreiter & schmidhuber (1997) and recently improved and promoted by Alex graves. In many problems, LSTM has achieved great success and has been widely used. LSTM is designed to avoid long-term dependency. Remember that long-term information is the default behavior of LSTM in practice, not the ability to acquire it at a great cost! All RNNs have a chained form of repetitive neural network modules. In the standard RNN, this repetitive module has only a very simple structure, such as a tanh layer.)

自适应滤波器算法与实现——最小均方误差LMS(Adaptive filter algorithm- least-mean-square error LMS)

说明：  这是一个利用GM(1,1)进行预测的matlab程序，是我在数模竞赛的时候写的，希望有用(This is a use of GM (1,1) to predict the matlab procedure is that I die in a few competitions when written in the hope that useful)

中值滤波窗口大小影响滤波器性能,3×3滤波窗口可以很好地保持图像细节。提出一种新的自适应中值滤波方法。将3×3窗口中心的极值点作为候选噪声点,若候选噪声点仍然是7×7窗口的极值点,则该点即是噪声点。若以噪声点为中心的3×3滤波窗口的中值不是噪声,则噪声用中值替换。重复以上过程,直到没有噪声点被替换。(Median filter window size affect the filter performance, 33 filter window can be well preserving image detail. Propose a new adaptive median filtering method. The 33 extreme point of the center of the window as the candidate noise the candidate noise is still 77 extreme points of the window, the point is that the noise point. Terms of noise centered on the point 33 filtering window value is not a noise, the noise is replaced with the median. The process is repeated until there is no noise point is replaced.)

说明：  matlab中位值滤波，可以对连续信号进行中位值滤波(matlab median filter, the signal can be continuous median filter)
