Canny Edge Detection

this code is for antenna wave propogation .............. and increase the num of iteration

在功率谱估计中采用Bartlett法对信号进行功率谱估计。(In the power spectrum estimation method used in Bartlett signal power spectrum estimation.)

This MATLAB implementation computes a correspondence between two shapes based on ant colony optimization (ACO). The input shapes can be either two 2D contours (open or closed) or two arbitrary sets of 2D points. The algorithm is described in detail in:

OFDM系统中限幅降低峰值与平均功率比的matlab实现，可以直接运行，会有点慢(OFDM system, limiting the peak to average power ratio reduction of the matlab implementation, can run a bit slow)

此程序用于对matlab 模拟退火算法的验证及应用(This procedure used for the validation and application of the Matlab simulated annealing algorithm)

The architecture of this set of codes and the interaction among them is shown in Figure 1. The main testing code main code.m calls the code riemann grad unit opt.m that performs Riemannian optimization under unitary matrix constraint. Steepest Descent/Ascent (SD/SA) algorithm (see Table 3.2 in [1]), Conjugate Gradient (CG-PR, CG-FR) algo- rithms (both Fletcher-Reeves and Polak-Ribi`ere formulas, see Table 3.3 in [1]), are im- plemented. This code further calls the codes implementing line search methods: Armijo method geod search armijo.m, as well as the polynomial and DFT-based approximation

免疫方法来解决TSP问题，方法不错，程序有注释(Immunological methods to solve TSP problem by good procedure Notes)

说明：  Levenberg-Marqardt最优迭代算法(Levenberg-Marqardt optimal iterative algorithm)

实现基于压缩感知理论的超声重构算法,其中包含SPGL1的工具包，在maltab中添加到路径即可(Based on the theory of compressed sensing reconstruction algorithm ultrasound)
