一个横好的谱估计算法，AM ma 和arma模型，可以自动的选取。(A good cross-spectral estimation algorithm, AM ma and arma model selection automatically.)

MATLAB在最优化中的应用，源码。希望对大家有帮助(MATLAB application in the optimization, the source code.I hope it can help you)

matlab中信噪比计算程序，可以检验使用matlab内置函数添加的噪声是否正确(Can be tested using matlab citic noise ratio calculation, matlab built-in functions to add noise is correct )

用MATLAB实现对同一声音信号的不同频率的采样速率输出幅度谱和相位谱。(MATLAB to the same acoustic signals of different frequency of the output amplitude spectrum and phase spectrum sampling rate.)

MATLAB是一种科学计算软件，专门以矩阵的形式处理数据。MATLAB将高性能的数值计算和可视化集成在一起，并提供了大量的内置函数，从而使其被广泛地应用于科学计算、控制系统、信息处理等领域的分析、仿真和设计工作中，而且利用MATLAB产品的开放式结构，用户可以非常容易地对MATLAB的功能进行扩充，从而在不断深化对问题认识的同时，逐步完善MATLAB产品以提高产品自身的竞争能力。 (MATLAB is a scientific computing software, and specialized form of a matrix data processing. MATLAB will be high-performance numeric computation and visualization integrated and provides a number of built-in function, so that it is widely used in scientific computing, control systems, information processing, analysis, simulation and design work , and the use of the open architecture of MATLAB product, the user can very easy expansion of the MATLAB functions, thus deepening the understanding of the problem, and gradually perfect the MATLAB products to enhance the competitiveness of the product itself.)
