说明：  蚁群算法在tsp（旅行商问题)的matlab程序。可以运行。(Ant colony algorithm in tsp (TSP) of the matlab program. Can run.)

说明：  时频分析工具箱，还有说明和源程序。很好的东西(Time-frequency analysis toolbox, as well as notes and source code)

采用时频聚集性较好的线性调频信号作为线性时不变系统输入激励，采用Gabor字典作为过完备原子库。在利用传统系统辨识法之前先利用稀疏分解算法将输出信号进行去噪处理，显著提高系统辨识精度。 具体包括互谱算法，信号的Gabor稀疏分解的详细代码(Space can be a time for sparse decomposition to solve the problem of huge memory needed。This approach, combined with the rapid decomposition of FFT for signal ,so as to achieve satisfactory results.)

说明：  A星算法，可以实现三维路径规划，对路径规划和A星算法感兴趣的可以借鉴参考(A-star algorithm, can achieve three-dimensional path planning, path planning and A-star algorithm interested can refer to)

MATLAB/SIMULINK BASED NON Linear Control of PUMA 560

This script shows orthogonallity between sub-carriers in OFDM is realized when signals complete integer number of cycles over same number of samples.

说明：  利用双线性变换法设计一个级联型的椭圆IIR滤波器，对一段含噪语音信号进行滤波去噪处理并根据滤波前后的波形和频谱分析滤波性能。本课程设计仿真平台为MATLAB7.0，开发工具是M语言编程。首先在Windows下用录音机工具录制一段语音信号，并人为加入一单频噪声，然后对信号进行频谱分析以确定所加噪声频率，并设计滤波器进行滤波去噪处理，最后比较滤波前后的波形和频谱并进行分析。(Bilinear transformation method is used to design a cascade elliptic IIR filter, for a period of noise speech signal filtering denoising processing and according to the waveform and spectrum analysis of filtering performance before and after filtering. This course design simulation platform for the MATLAB7.0, development tools is M language programming. First under Windows tool to record a voice signal, a tape recorder and deliberately added a single frequency noise, and then the signal to determine the added noise frequency spectrum analysis, and design the filter for filtering denoising processing, finally compared before and after the waveform and spectrum of filtering and analyzed. )
