智能绘制风玫瑰图。采用十六分，方向的表示方法。(Smart draw wind roses. 16 points the direction of said。)

有关matlan中 双曲抛物面 的源代码，此代码较别的代码更假简单(Related matlan hyperbolic paraboloid source code, this code is more false than the other code and simple)

增广最小二乘法的程序，通过程序可以明确原理。适应性好~(Least squares procedures augmented by the program can clear principles. Adaptability ~)

说明：  处理数据中有很好的应用，里面有验证函数，可以进行验证。(Processing data has a good application, there are validation functions, can be validated.)

以Matlab为应用背景，比较详细地介绍了根轨迹图的制作。(Examples on Root Locus Plot.)

在工程应用中 经常会遇到一些复杂的非线性系统, 这些系统状态方程复杂, 难以 用数学方 法准确建模。 在这种情况下, 可以 建立 BP 神 经网 络表达这些 非 线 性系 统。 该方法把未 知 系 统看成是一个黑箱, 首先用 系 统 输入输出 数据 训 练 BP 神 经网 络, 使网 络能 够表达该未 知 函 数, 然后就可以 用训练好的 BP 神经网络预测系统输出 。 本章拟合的非线性函 数为 y = x1^2+x2^2. 。 (In engineering applications often encounter some complex nonlinear systems, which complicated the equation of state, can not be accurately modeled mathematically. In this case, BP neural network can be established to express these nonlinear systems. The method of the unknown system as a black box, the first input and output data with systematic training BP neural network, the network can express the unknown function, then you can use the trained BP neural network forecasting system output. Chapter for fitting non-linear function y = x1 ^ 2+x2 ^ 2..)
