MATLAB70ch4

matlab扩展编程：增加了matlab的数据结构和编程技巧，c调用matlab，matlab访问硬件系统，matlab录音工具，matlab的语音识别系统等(matlab expand programming: an increase of matlab data structures and programming techniques, c call matlab, matlab access to hardware system, matlab recording tools, matlab voice recognition systems, etc.)

此程序用于实现结构的有限元计算：将patran中的模型的bdf文件中的单元信息和节点信息保存成txt文档，在matlab中调用，就可实现刚度矩阵、质量矩阵的组装，进而有限元计算(This procedure is used to achieve the structure of the finite element method: bdf file of the model in patran unit information and node information is saved into a txt file called in matlab, you can achieve the stiffness matrix, mass matrix assembly, and then the finite elementcalculate)

说明：  分数阶灰色单变量预测模型，可用于小样本不确定序列时间序列预测(time series forecasting)

隐马尔科夫工具箱。可在matlab6.5中创建成用户工具箱。(Hidden Markov toolbox. Matlab6.5 be created into user toolbox.)

Bag of features source code developed in matlab. It contains mex files for clustering and eucledian distance.

基于MATLAB的IIR滤波器设计，用MATLAB语言进行编程，供滤波器设计者参考(Based on the MATLAB IIR filter designing, MATLAB programming language, for filter designers)

说明：  vhdl 初学例程，对于初学者有很大的参考价值哦(VHDL beginner routines for beginners have great reference value oh)

PID控制模型，可以进行多种控制的仿真实验，经本人实验无错误码，可正常运行(PID control model, the simulation can be a variety of control experiments, the experimental error-free code I can be normal operation)

fsolve求解非线性方程组，代码可以十分准确的求解方程组，方便快捷(fsolve solve nonlinear equations, the code can be very accurately solving equations, convenient)

说明：  MATLAB编写的数值分析实验的一些小程序(MATLAB prepared by the numerical analysis of a number of small experimental procedure)
