DiscriminantMethods

说明：  本程序实现了8DPSK的调制与传输，计算了误码率等性能参数(This procedure implements the modulation and transmission 8DPSK calculated performance parameters such as bit error rate)

说明：  在matlab中实现高斯序列，三角序列，反三角序列等，分析其频谱特性(In matlab to achieve Gaussian sequence, triangular series, the anti-triangular sequence and so on, to analyze its spectrum characteristics)

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..)

一种全局的直接优化方法，优化过程中无需用到目标函数的导数信息。(The purpose of this brief user guide is to introduce the reader to the DIRECT optimization algorithm, describe the type of problems it solves, how to use the accompanying MATLAB program, direct.m, and provide a synopis of how it searches for the global minium.)

duffing方程的混沌判别中使用到了庞加莱截面，即多维相空间中适当选取一截面 ，此截面不与轨线相切，不包含轨线，且便于观察系统的运动特征变化.(use Poincare chaotic duffing equation discriminant, multi-dimensional phase space appropriate to select a cross-section, this section is not tangent to the trajectory does not contain the rail line, and easy motion characteristics of the observed system changes.)
