卷积神经网络是人工神经网络的一种，已成为当前语音分析和图像识别领域的研究热点。它的权值共享网络结构使之更类似于生物神经网络，降低了网络模型的复杂度，减少了权值的数量。自己可已加入数据，和修改梯度。(Convolutional neural network is an artificial neural network, it has become a research hotspot speech analysis and image recognition field. It weights shared network structure to make it more similar to biological neural networks, reduce the complexity of the network model, reducing the number of weights. Own data may have been added, and modify gradients.)

此程序是关于经济学中布莱克斯科尔斯模型 的matlab实现(This procedure creates a three-dimensional plot showing how gamma changes relative to price for a Black-Scholes option. Recall that gamma is the second derivative of the option price relative to the underlying security price. The plot shows a three-dimensional surface whose z-value is the gamma of an option as price (x-axis) and time (y-axis) vary. It adds yet a fourth dimension by showing option delta (the first derivative of option price to security price) as the color of the surface)

　用水量预测在城市建设规划、供水系统的调度 管理中都具有重要作用。常用的预测方法可分为两 类,一类是解释性预测方法,即找出被预测量的各影 响因素,建立回归分析模型(Water demand in urban planning, regulation and management of water systems has an important role. Commonly used forecasting methods can be divided into two categories, one is an explanatory forecasting method, which is predicted to identify the amount of the influencing factors, a regression analysis model)

一种变步长LMS的算法，描述了与基本LMS算法的比较，随着迭代次数的增加，变步长的LMS算法达到最优的迭代次数少(A variable step size LMS algorithm, describes the basic LMS algorithm and compare that with the increase in the number of iterations, variable step size LMS algorithm to achieve the optimal number of iterations less)
