基于matlab编写，是一段生成word文档的小程序，文档中有一个表格，希望对大家编写输出数据程序有帮助(Matlab-based development, is a word document to generate a small program, a form document, prepared for all of us hope that the process output data to help)

matlab实现arima算法,这个代码里面有一个循环过程来选择合适的阶(arima algorithe)

这是龚纯《精通MATLAB最优化计算》随书源码(M文件)。基于MATLAB优化工具箱，代码包含的内容有：牛顿法等无约束一维极值问题、单纯形搜索法等无约束多维极值问题、Rosen梯度投影法等约束优化问题、L-M法等非线性最小二乘优化问题、线性规划、整数规划、二次规划、粒子群优化、遗传算法。(This is pure Gong " Mastering MATLAB optimization calculations," with the book source (M file). Based on MATLAB Optimization Toolbox, the content code contains: Newton and other non-binding one-dimensional extremum problems, such as simplex search method for unconstrained multi-dimensional extremum problems, Rosen gradient projection method and other constrained optimization problems, LM non-linear law least squares optimization problem, linear programming, integer programming, quadratic programming, particle swarm optimization, genetic algorithm.)

大学时候跟导师做的一个暂态电磁场数据分析的程序，用于自动检测和识别波形数据中的脉冲起始时间等参数(University instructors often do with a transient electromagnetic field data analysis procedures, for the automatic detection and identification of waveform data pulse parameters, such as start-up time)

实现滤波器的功能，从而使有噪声的图像得以修复。(Realization of the filter function, so there is noise in the image can be repaired.)

我最近写的一篇论文的源码，主要是对带参考信号的 ICA算法的扩展，多参考信号的ICA固定点算法。(I recently wrote a paper source, mainly for reference signal with the ICA algorithm expansion more reference signal ICA fixed-point algorithms. )
