对灰度图像采用Arnold混沌加密，实现图像置乱加密(By Arnold on the gray image encryption, encryption of image scrambling)

经典的标量JA 模型的代码，非常适合磁滞模型初学者 我给出了两种实现方式的代码 一个用固定点迭代实现，可以容易变成c语言 另一个使用simulink 实现，可以加到控制图中作为一个子函数(the code is programmed following the classical paper of D.Jiles ,fellow of IEEE. The JA model is great and innovative work in magnetic material.)

用径向基神经网络和BP网络预测的源码，径向基神经网络优于BP网络预测。(With RBF neural network and BP network prediction source, RBF neural network is better than BP network prediction.)

The time-independent behaviour of this approach is necessary to assure the correct tracking

曲线回归分析：直线回归、双对数回归、半对数回归、倒数回归(Curvilinear regression analysis: linear regression, double logarithmic regression, semi-logarithmic regression, countdown)

说明：   实 现 Cholesky(Cholesky)

小波分析因其在处理非平稳信号中的独特优势而成为信号处理中的一个重要研究方向。如今随着小波理论体系的不断完善，小波以其时频局部化特性与多尺度特性在图像边缘检测领域中倍受青睐。(Wavelet analysis of nonstationary signal processing because of its unique advantage in signal processing and become an important research direction in. Now with the wavelet theory system ceaseless and perfect, the time-frequency localization characteristic of wavelet based and multi scale characteristics in the image edge detection is very popular.)

卷积码的matlab仿真，经由simulink搭建的系统平台(Convolutional codes matlab simulation platform erected by simulink)

说明：  拉普拉斯高斯算子 拉普拉斯—高斯算子（Laplacian of Gaussian算子，通常缩写为log算子）是一种二阶微分算子，将在边缘处产生一个陡峭的零交叉。(Laplace Gaussian operator Laplace- Gaussian operator (Laplacian of Gaussian operator, often abbreviated as log operator) is a second-order differential operator, will be generated at the edge of a steep zero crossing.)
