灵敏度分析源程序，可用于结构模型修正，但仅运用了自振频率信息，没有运用振型信息(Sensitivity analysis of source code, can be used for structural model updating, but only the use of natural frequency information, there is no information on the use of modal)

语音信号去噪，在MATLAB开发环境下，对含噪声的语音信号进行小波变换，实现语音增强的功能。(The speech signal denoising, wavelet transform, the noisy speech signal in the MATLAB development environment, Speech enhancement functions.)

通过粒子群算法快速解决旅行商问题,其中还可以自己设置参数，学习因子，惯性权重等。(Through particle swarm algorithm quickly solve traveling salesman problem, which can still parameters, the learning factor, self-adapting inertia, etc. )

A sound source can be localized in a two dimensional plane using the audio recorded at three known microphone locations. Much like a GPS system, Time Difference of Arrival algorithms can be used to determine the difference in time and distance of a sound source to other microphones. With that information a Chan algorithm can be used to determine the X Y coordinates of the originating sound source. To do so, however, you must first provide the XY coordinates of each of the 3 microphones. Note that for faster and simpler calculation one of the microphones should be placed at the origin (0, 0) of you XY plane.
