对图像进行滤波的几种算法集锦，并在同幅图中显示，便于对比其各种效果，另外给出了一副彩色图像的滤波效果，还请高手指点。(Image filtering allehanda Algorithms, and at the same pictures shown to facilitate comparison of its various effects, another is given a color image filter effects, also requested the expert advice.)

主要用于对含有噪声的信号进行降噪处理，先小波包降噪再奇异值降噪(It is mainly used to denoise the signal containing noise. First, the wavelet packet de-noising and then the singular value denoising)

用LAPLACE方法求解多维沃尔泰拉方程，此处为一个变元的方程，由于该方程同时含有微分和积分，一般求解有一定的困难。此处为MATLAB程序，注意不同的初始条件(used method for multiple preoperational Ertaila equation here as a variable element of the equation, As the same time contain differential equations and integral, the general solution is definitely difficult. MATLAB here for the procedure to different initial conditions)

模拟退火算法训练程序，结合了BP神经网络算法(The simulated annealing algorithm for the training program, combined with the BP neural network algorithm)

对典型混沌进行仿真，有程序，图像，明白易懂(Simulation of typical chaotic)

在过阻尼情况下，典型二阶系统有两个相异的实数极点，其阶跃响应实际上是两个一阶系统响应的叠加。（ωn＝5），不断增大ζ值，观察每个ζ值下两个实数极点间的距离；同时绘出两个实数极点分别对应的一阶系统响应和二阶系统的响应，观察它们间的关系(In the overdamped case, the typical second-order system has two distinct real poles, and its step response is actually the superposition of the two first-order system response. (Wn = 5), increasing zeta values​ ​ , observing the distance between the two real poles each zeta value draw two real poles, respectively, corresponding to a first-order system response and the response of the second-order system, observe them relationship)

对于一个动态系统dy/dt=-y(t)+x(t-m),m为一个时间滞后常量，x(t)、y(t)都是关于时间 t的函数，其中x是一个正态分布的数据集合，可随机产生，这样情况下，如何将系统情况 用样本点表示出来 (for a dynamic system dy/dt =- y (t) x (t-m), m for a time lag constants, x (t), y (t) are on the function of time t, where x is a normal distribution of data sets can be randomly generated, under these circumstances, how the system of sample points out)

介绍的是对于钙信号传导的某种简化模型的模拟(Described the simulation of a simplified model for calcium signaling)
