神经网络是单个并行处理元素的集合，我们从生物学神经系统得到启发。在自然界，网 络功能主要由神经节决定，我们可以通过改变连接点的权重来训练神经网络完成特定的功能。如人脑的某一部分进行机械记忆特别有效 而某一部分进行抽象思维特别有效。(Nervous system has some functions. Here I make them by using Matlab.)

关于近来很火的灰色预测理论的matlab的源代码，移植性好，与诸位学友共同分享，共同进步(About the grey prediction theory recently very fire matlab source code, good portability, xueyou with share, make progress together)

MATLAB编程（英文影印版第二版），malab编程的经典教材，适合学习与作为工具书查阅(MATLAB programming (English version of the second edition of a photocopy), malab classic programming materials ， the book can be used as a tool for learning)

This tutorial starts with a simple conceptual model of an analog Phase-Locked Loop (PLL). Through elaboration it ends at a model of an all digital and fixed-point phase-locked loop. The final model can serve a starting point for code generation (both ANSI C or synthesizable HDL). The step-wise elaboration of the model illustrates how Simulink® forms the basis a model-based design where continuous verification of the model reduces errors.

实现一个LCC滤波器的Matlab程序实现，在matlab6.5调试通过(Digital filter realization of Matlab procedures)

自己编写的对一幅图像实现最近邻插值和双线性插值，可以直接运行，效果很好。(Write your own images of a nearest neighbor interpolation and bilinear interpolation, can be run directly, the effect is very good.)

状态子空间的MPC程序段，N4SID算法，可以直接在matlab中使用(The state subspace MPC block, N4SID algorithm, can be directly used in matlab)

西安交通大学开的《图象处理》的课，用的课本是章毓晋老师编的《图象工程》上册，既《图象处理和分析》，我本科期间学的这门课，这是用MATLAB所做的作业源程序，包括颜色模型转换成，直方图转换，图象分割，边缘检测，hough变换（哈夫变换），图象表达等。(Xi'an Jiaotong University opened the "image processing" of the class, Textbooks are used in Yu-Jin Zhang teachers are "image projects" on the list, both "image processing and analysis" During my undergraduate study of this course, this is done using MATLAB source operations, including the color model conversion. Histogram conversion, image segmentation, edge detection, hough transform (Hough transform), image expression.)
