本软件主要用于结构的时域试验模态分析，包括单输入单输出，单输入多输出和多输入多输出程序设计。传统的模态分析软件大多是基于频域分析方法，需首先对采样信号进行Fourier 变换。本软件使用实测时域信号，无需Fourier变换，可以避免由于信号截断而引起泄露、出现旁瓣、分辨率低等问题对辨识精度的不利影响。此外，节省了计算机运算时间，可以对实际工况状态下的结构进行在线参数识别。(This software is mainly used for the structure of time-domain experimental modal analysis, including single-input single-output, single-input multiple-output and multiple-input multiple-output programming. Traditional modal analysis software are mostly based on frequency domain analysis, needed first sampled signal Fourier transform. The software uses the measured time-domain signal without the need for Fourier transform, avoid truncated because of the signal caused by leaks, there sidelobes and low resolution of the issue of adverse effects on the identification accuracy. In addition, the savings in computing time, to the actual condition of the structure of the state-line parameter identification.)

差值、函数逼近、矩阵特征值计算、数值微分、数值积分、方程求根、非线性方程组求解、线性方程组直接法、线性方程组迭代法、随机数生成、特殊函数计算、常微分方程初值问题、偏微分方程数值解法、数据统计和分析(Difference, function approximation, eigenvalue calculation, numerical differentiation, numerical integration, finding roots of equations, nonlinear equations, linear equations, direct method, iterative linear equations, random number generator, a special function to calculate , initial value problems of ordinary differential equations, numerical solution of partial differential equations, statistics and analysis)

Mann-Kendall Tau-b非线性函数，用于时间序列分析中计算平均变化趋势。(The Mann-Kendall Tau-b non-parametric function computes a coefficient representing strength and direction of a trend for equally spaced data. While you do not need the Statistics Toolbox to compute Taub, you do need it to test for significance. This function will compute Tau-b (now tau-a as well), significance (and the various supporting statistics), and also a non-parametric slope method: Sens Method. )

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.)

相干源对最大似然算法测向的影响 设置了两个相干的信号，以便研究相干源对测向的影响(Coherent Sources on the maximum likelihood algorithm for measuring the impact of the establishment of two coherent signals, in order to study the coherent source of measurement to the effects of)

This script illustrates the fading in gmsk under nakagami distribution.A reference paper is also included.

共轭梯度法，是数值分析中很重要的一种，源码为其在matlab中的实现。(Conjugate gradient method, numerical analysis is a very important one in the matlab source code for its realization.)
