说明：  蚁群算法求解TSP问题,非常简单，绝对可用(ant swarm to solve the problem of tsp )

this function use clustering to find out the RBF network centres

用巴特沃兹低通（高通）、高斯低通（高通）、拉普拉斯高通滤波器对图像进行平滑（锐化）处理，以及Unsharp mask与highboost filtering(Butterworth low-pass (high-pass), Gaussian low-pass (high-pass), Laplacian high-pass filter on the image smoothing (sharpening) processing, and Unsharp mask highboost filtering)

基于matlab的粒子群优化算法，并且包含几种典型的测试函数(A Matlab optimization algorithm based on particle swarm, and contains several typical test functions.)

OFDM系统的MTLAB程序仿真，对于刚入门学OFDM的新手来说很有帮助(OFDM system MTLAB process simulation, for the novice just started learning it was helpful for OFDM)

灰度图像的增强，效果相当可以，可以实现灰度图像的对比度增强(Gray-scale image enhancement, the effect can be considerable, can enhance the contrast of gray image)

地震波有限差分matlab模拟程序，输出可以为SGY格式，模拟地震波在地下介质中的传播(Seismic wave finite difference simulation program matlab, the output can be SGY format, simulate the propagation of seismic wave in underground medium )

基于matlab的QPSK信号生成，已加噪。(QPSK signal generated)

说明：  哈工大matlab 讲义 希望对大家有用 对于刚开始学的有作用(HIT matlab useful handouts hope for all of us are just beginning to learn about the role of)

It is a function of active disturbance reject control
